Female Education Essay

Napoleon once said â€Å"Give me an educated mother and I will give you an educated nation. † This statement is enough to prove the importance of female education. Allah has created both man and woman equally. They are like the two sides of a coin. One is incomplete without the other. So, education cannot be the only possession of a single class or sex. Rather, it should be imparted equally to both men and women. Our religion has also made education compulsory for all. In the past, our women folk were confined within the four walls of home. Parents did not allow them to receive education and to participate in any outside work. Early marriage, religious misinterpretation and the narrowness of our outlook were mainly responsible for this. Parents thought it waste of time and money to educate their girls. They did not understand that if girl children were educated they could be as competent as male children. As our women folk constitute almost half of our total population, no real development is possible keeping them uneducated. On the other hand, an educated mother plays a very important role in making and shaping the character of her children. She knows well how to bring up her children, to educate them and to make them worthy. In domestic life, she can also extend her helping hand to her husband. So, there is no alternative to female education. It is a matter of great delight that women have started to come out of their cocoons. Being educated, they are joining a wide range of professions. They have been able to prove their abilities. So, the disadvantages of early marriage and religious misinterpretation must be removed. Our outlook about women must be changed. More schools and colleges for girls should be set up to spread female education. Recently the scenario of female education has started to change. Many socio-economic factors are responsible for this change. All possible facilities of female education have been extended. Education for girls up to degree level has been made free with a monthly stipend. This encourages them to continue their education. We should remember that only educated women can change the picture of our society. So, all of us should come forward to spread female education. The overall state of female education in Bangladesh is not yet satisfactory. In the past, women were in the boundary of their houses. They usually spent their time doing their household chores. They were deprived of education. But the situation has been changed now. Now-a-days, they are admitting into schools, colleges and universities. The rate of literacy in our country is about 60% whereas female literacy is about 40%. Female education is necessary for getting an educated nation. Because, an educated mother can give an educated nation. There are many advantages of female education. A child will never remain illiterate if his/her mother is educated. An educated woman can play various roles in the family. She can impart himself in different business and jobs. As a result, she can contribute to the family income. However, government should do something more to educate the female. â€Å"No need girl’s education, they are born only for taking care of their families†- this idea was stereotype in the early past of Bangladesh. The birth of a boy child was a blessing for the parents and a girl child was like a curse. It is a surprising matter that a girl child also comes like a boy child from mother’s womb and father’s blood but still that child is unexpected to her parents. In reality, a father and mother can never hate their children. Actually, the society made the rule to neglect the girl children. As Bangladesh is considers as a Muslim country, most of its population are Muslim. The Bangladeshi people thought that their religion had ordered them to keep their women and female children inside the house and keep them in safe. As a result, the parents always wanted a male child to earn for the family and protect their old age. From a theological research, it has found that the beliefs which were followed by our ancestors were based on wrong concepts. The holy books actually suggested keeping women in safe, not to confine them into four walls where they do not have any liberty. These books also suggested that a woman can even participate in the warfare if she is able to protect herself. Very slowly but the people started to change their mentality when they were becoming educated and started realizing that it was useless to achieve success without women as a mother is the first teacher of a child. If a mother is illiterate there is much possibility that the child will be uneducated. To cure this problem, Begum Rokeya, the pioneer of giving the light of education to the Muslim Bengali girls. This social movement of educating girls was very slow and at that time people were against of this blessed work. She kept patience and opened a girls’ school. She made people to understand about the benefit of the girl’s education by giving the religious points. Though it took time to convince people, it worked. People understood the necessity of the girls’ education and started sending their daughters into the school. This idea was so effective because a nation can have more achievements if the entire nation works together for success, not the half of the nation. The government also realized that this is an innovative idea and so the†¦ â€Å"It is the height of selfishness for men, who fully appreciate in their own case the great advantage of a good education, to deny these advantages to women. There is no valid argument by which the exclusion of the female sex from the privilege of education can be defended. It is argued that women have their domestic duties to perform and that, if they were educated, they would bury themselves in their books and have little time for attending to the management of their households. Of course, it is possible for women as it is for men to neglect work in order to spare more time for reading sensational novels. But women are no more liable to this temptation than men and most women would be able to do their household work the entire better for being able to refresh their minds in the intervals of leisure with a little reading. Nay, education would even help them in the performance of the narrowest sphere of womanly duty. For education involves knowledge of the means by which health may be preserved and enable a mother to consult such modern books as will tell her how to rear up her children into healthy men and women and skillfully nurse them and her husband, when disease attacks her household. Without education she will not be averse to listen, with fatal results, to the advice of superstitious quacks that pretend to work wonder by charms and magic. But, according to higher conception of women’s sphere, women ought to be something more than a household drudge. She ought to be able not merely to nurse her husband in sickness but also to be his companion in health. For this part of her wifely duty, education is necessary, for there cannot be congenial companionship between an educated husband and an uneducated wife who can converse with her husband on no higher subject than cookery and servant’s wages. Also, one of a mother’s highest duties is the education of her children at the time when their mind is not amenable to instruction. A child’s whole future life, to a large extent, depends on the teaching it receives in early childhood and it is needless to say that this first foundation of education cannot be well laid by an ignorant mother. On all these grounds female education is a vital necessity. Gender inequality in education is extreme. Girls are less likely to access school, to remain in school or to achieve in education. Education helps men and women claim their rights and realise their potential in the economic, political and social arenas. It is also the single most powerful way to lift people out of poverty. Education plays a particularly important role as a foundation for girls’ development towards adult life. It should be an intrinsic part of any strategy to address the gender-based discrimination against women and girls that remains prevalent in many societies. The following links will further explain the necessity of girls’/women’s education. Education is a right Cultural changes Better health and awareness Poverty reduction Education is a right Everybody has the right to education, which has been recognised since the Universal Declaration of Human Rights (UDHR) in 1948. The right to free and compulsory primary education, without discrimination and of good quality, has been reaffirmed in all major international human rights conventions. Many of these same instruments encourage, but do not guarantee, post-primary education. These rights have been further elaborated to address issues like quality and equity, moving forward the issue of what the right to education means, and exploring how it can be achieved. As a minimum: states must ensure that basic education is available, accessible, acceptable and adaptable for all. (4A scheme) The right of girls to education is one of the most critical of all rights – because education plays an important role in enabling girls and women to secure other rights. Cultural changes Cultural and traditional values stand between girls and their prospects for education. The achievement of girls’ right to education can address some of societies’ deeply rooted inequalities, which condemn millions of girls to a life without quality education – and, therefore, also all too often to a life of missed opportunities. Improving educational opportunities for girls and women helps them to develop skills that allow them to make decisions and influence community change in key areas. One reason for denying girls and women their right to an education is rarely articulated by those in charge: that is their fear of the power that girls will have through education. There is still some resistance to the idea that girls and women can be trusted with education. Education is also seen in some societies as a fear of change and now with globalization, the fear becomes even greater- fear to lose the cultural identity, fear of moving towards the unknown or the unwanted, fear of dissolving in the many others. Better health Basic education provides girls and women with an understanding of basic health, nutrition and family planning, giving them choices and the power to decide over their own lives and bodies. Women’s education leads directly to better reproductive health, improved family health, economic growth, for the family and for society, as well as lower rates of child mortality and malnutrition. It is also key in the fight against the spread of HIV & AIDS. Poverty reduction Educating girls and women is an important step in overcoming poverty. Inequality and poverty are not inevitable. â€Å"The focus on poverty reduction enables the right to education to be a powerful tool in making a change in the lives of girls and women. Poverty has been universally affirmed as a key obstacle to the enjoyment of human rights, and it has a visible gender profile. The main reason for this is the fact that poverty results from violations of human rights, including the right to education, which disproportionately affect girls and women. Various grounds of discrimination combine, trapping girls in a vicious downward circle of denied rights. Denial of the right to education leads to exclusion from the labour market and marginalisation into the informal sector or unpaid work. This perpetuates and increases women’s poverty. † Education is one of the basic human rights. Every human being has the right to be enlightened by the light of knowledge. But like other issues of our society, a gender inequality exists in receiving education which is enacted to the females. This unwanted practice is continuing still in our society and hinders the progress of our nation. In our country, because of some old superstitions and customs, girls are deprived from many facilities which are cashed in on by males. Education is one of those. The parents think not to invest money to their female children rather than to the males. And that’s why; women of our country still can’t lead a solvent, secured, independent life. A woman without any education can’t use her skills and brain in a proper way. Because of educational ignorance, she can’t differentiate the right and wrong and take any decision correctly. She can’t use the chances to uplift her condition. She can’t nurse her family and children properly. In total, an uneducated woman leads a disorganized life. These awful facts affect the society decisively. Almost half of the population remains inoperative, unskilled, and slapdash. It lags behind the whole nation economically, academically, commercially which will suffer the future generation. If the women-folk is educated, they can utilize their skill, knowledge and work hand in hand with men in all programs of development. They can be self-employed and be a source of man power by which they can support their family financially. They can analysis any situation and take the right decision and influence her family and society in the key areas through their useful thoughts. They will be conscious about early marriage, family planning, maternal mortality rate, child mortality etc. Besides, if a woman is educated, she can take care of her children perfectly. A mother exercises an undeniable influence in the formation of children’s character and shaping their future destination. Once Napoleon said, â€Å"Give me†¦ [continues] Essay Introduction: The history of progress of the human race is the history of education. Hence it is necessary for every person, man or woman, to be educated. The hand that rocks the cradle rules the world. Women should be educated like men; otherwise there can be no peace or no progress. If you yoke an unbroken (untrained) horse with highly trained one, the carriage will be dashed to pieces sand the occupants’ lives will be destroyed. The family peace cannot be preserved with such ill-matched life-long companions. Need for Female Education: Napoleon was once asked what the greatest need of France was. He answered â€Å"Motherland’s National progress is impossible without trained and educated mothers. † If the women in any country are not educated about half the people in that country will be ignorant. The result is that such a country will not be able to go along with other nations in development and progress. A Controversy: There is a great controversy going on in India whether women should receive higher education or not. Orthodox people are in favor of female education, but they are opposed to given them high education. But this view does not sound well. If women are mentally fit to receive higher education there seems to be no reason why they should not be allowed to develop their mental faculties. There is other group of liberal people which in favor of the female education. To give them only the rudiments of knowledge while they are eager for advanced studies is to condemn them to a place of inferiority. Duties of Woman: A woman has to play three distinct parts in the course of her life in each of which certain duties are expected of her. If she is able to do these well she is worthy of being called perfect woman. It is only by the help of education that she can hope to be able to do them satisfactorily. The first duty of a woman is to be a good daughter. The second is to be a good wife. And the third is to be a good mother. Education†¦ [continues] Male Female Education Different people have different ideas and opinions as to whether it is more important to educate boys or girls. Some believe that the education of boys is more important than that of the girls, and meanwhile others disagree. In reality, the choice depends on what country, culture, or society we are talking about. In many nations including many Asian countries, tradition demands that men provide the family with income, food, clothing, etc., and women perform the usual household business such as cooking, cleaning, washing, and taking care of children. In such societies it seems logical that there is more stress on the priority of men’s education rather than women, since it is the male that requires the needed education to succeed, survive, and thrive. It is perceived in these countries that education is not of vital importance to women since they â€Å"are not† supposed to work outside the house, and that their primary duty is to take care of the family and kids. However in modern societies and nations, the situation differs. Now days more countries are inclined towards modernization. The general moral philosophy of these nations is equality amongst men and women; therefore, this means equal business, industrial, and occupational opportunities for both the men and women. Based on these facts, it is vital to put of equal stress on the education of men and women for this will insure that females and males perform their tasks professionally and adequately. In my opinion, the edification of men and women has to be equally emphasized because today’s technological and economical advanced world require fully educated, experienced, and versatile citizens regardless of their gender. And this can be only achieved through sufficient education of both men and women. The importance of today’s society is to improve the reaction time interview tested techniques of the oriental and occidental countries and continents. [continues].

Marketing the McDonalds meat product is an important bit of the company because of what the product has to the company. Following several campaigns in the market posting fast foods served at the restaurants as unfit for consumption and other campaigns posting McDonalds Company as working behind a mask, there has developed negative attitude from the customers who are sourced globally (Evenson, 2010). In one of the campaigns it was posted that the company has failed to offer safe meat. The pro-vegetarianism have insisted on the informing the public about the unfitness of meat and meat product consumption. On the other hand the global move towards green meat is impacting on the meat products in the company especially in the times when the world is experiencing cases of zoonotic diseases like flu and mad cow diseases. Given the circumstances the company may not be able to effectively

Improving Waste Management Strategies for Small Livestock Farms Term Paper

Improving Waste Management Strategies for Small Livestock Farms - Term Paper Example The operations of CAFOs lead to production of wastes like manure, litter and the waste water from operations. They are known to have a high content of nitrogen, phosphorus, other metals and a host of harmful bacteria if not managed all these harmful substances can easily get into the environment. It is of importance that factors should put in place to prevent pollution from these small AFOs. The average size of farms has increased steadily over the last several years of this is due to the lucrative livestock industry, which has been known to yield high profits. Six major air pollutants have been identified as coming from AFOs areas or any animal housing areas, animal waste treatment areas they are known to highly contribute to the greenhouse gas emissions. They Include; ammonia nitrous oxide, methane, hydrogen sulfide, carbon dioxide. The best way to combat these in small farms is in the building of bio gas digesters, which provide cooking gases well as electricity and harness danger ous gases like methane preventing it from getting into the atmosphere (Ciravolo p 259). Though this has been known to be a capital intensive venture individuals, may form small organizations with a cooperative like to set up so that they can put the necessary infrastructure in place for the harnessing of these gases. This will also enable them to harness these gases in large scales, and this can lead to a viable economic return from its sales in the neighboring households. However, this is not a new approach and the stakeholders have to embrace technological means to ensure that they have the best approach to guarantee a clean environment as well as an effective conducive environment to coexist with other small scale farmers. Another major contributor is the odorous gases which lead to anaerobic degradation. Anaerobic degradation involves the decline of composite organic compounds to a range of odorous VFAs by bacteria that form acids. These bacteria alter VFAs to odorless methane a nd carbon dioxide. If these anaerobic components are in equilibrium, most redolent compounds are removed. The governments ought to recognize the status of small-scale livestock farmers and offer incentives to enable them to efficiently deal with waste management. This may be in the form of subsidies, or tax waivers for those who efficiently comply with the regulations put in place. Manure is a byproduct of the whole aspect of livestock production though it is normally viewed as a useful by-product mostly by the farmers. It still poses serious environmental problems if not utilized, applied or disposed in the right manner. Manure contains pathogens and bacteria from within the systems of these animals eliminated as waste products. These pose a big challenge to even the farmers themselves. Pathogens also pose a major challenge; it mainly gets its way to underground water percolation Percolating water provides the adequate mechanism for percolation of microorganisms through soil profil es. In inundated flow, water passes the soil filtering process thus; taking microorganisms with it through the soil profile the best way to address the pathogen problem is by carrying out process like air drying. Air drying is the process through which Animal wastes like manure is desiccated on sand beds basins or any other exposure to the

The different factors and effects of Air Pollution policies between Essay

The different factors and effects of Air Pollution policies between China and UK - Essay Example According to Gurjar, Molina and Ojha, air polluting emissions â€Å"occur at many stages in the life cycles of products and services, that is, from raw material extraction, energy acquisition, production and manufacturing, use, reuse, recycling, through to ultimate disposal† (1). After being released, the emissions go through different chemical and physical changes leading to a variety of impacts on the environment and health of living things. In recent years, air pollution has caused harmful effects to human life. It has been realized that incidences of chronic illnesses have been constantly rising; the incidences and seriousness of acute illnesses have also increased, as well as mortality rates. Together with the health effects institute, Bates and Kennedy assert that â€Å"when air pollution began to have a significant deleterious effect on human life , it became necessary to discover and understand the links between emission sources and the air quality deterioration and h ealth effects they cause† (162). Currently, environmental social movement groups such as Greenpeace and Amnesty international are playing a significant role in influencing negotiations over environmental protection and management of oceans, the ozone layer, and nuclear deployments. In addition to that, they aid in enforcing national compliance with international mandates (Goodwin and Jasper 227). Scientist’s currently consider climate change, which is caused by air pollution as one of the most serious problems the world faces. Furthermore, the entire globe is also faced by the looming grave threat of global warming, which is a serious environmental security issue. In fact, climate change has a major impact on all aspects of human social and economic life (Yu 37). China’s Environmental History The environmental history of China is quite unique compared to that of other nations. Apart from being â€Å"one of the largest and most climatically diverse countries on t he planet† (Leibo 52), its population has been historically larger than that of other societies around the world. This â€Å"has seen Chinese territory significantly more impacted by human activity than the usual situation elsewhere† (Leibo 52). China was also among the most biologically diverse and affluent places on earth four thousand years ago. Ironically, the very rich biodiversity in China was the main explanation it has supported one-third of the human population at any given time. Initially, the effects of the large population on China’s environment were insignificant. However, with the subsequent spread and development of agriculture and clearance of farmland, the impact of the human population on the environment has become perceptible. The twentieth century has also been marked with the emergence of a consumer culture coupled with rapid industrialization. This has resulted in the rapid ecological degradation in China. Five Year Plan (1953-1957) and the Great Leap Forward (1958-1960) The five year (1953-1957) soviet inspired plan was adopted during the Chinese communist leader Mao Zedong’s era (Marks 273). This was due to his dissatisfaction with the Soviet model, because he concluded that it would lead the People’s Republic of China away from realizing their dream of attaining a socialist country. He instead adopted a ‘Maoist’ path, fast industrialization of a socialist China, with rapidly collectivized agriculture spearheading the

Short story - Essay Example He recently got a job and he wants to be on his own. He has been sick with his father’s constant nagging. He does not like to be exasperated by a man who acts like a woman and talks more than his mother might have done if she were alive. His father has been a widower since he was ten and he never remarried because he said he needs to be the mother and father to Greg. He seemed more like a mother to him though and that was what Greg hated most. He did not like his extra care. He was quite possessive and perceived him like he was a helpless girl who does not know how to defend himself. His father has always been there for him and he got sick of him. He now has his opportunity of a lifetime. He will be just a few miles away but they both know that Greg has no plans of visiting his father for a long time. He clearly pointed out that he will be sending his dad monthly allowances and food supplies. His father started to talk but Greg was already feeling exhausted with their conversation. He glanced at his watch without really checking the time and he said, â€Å"I must go. I still have a long drive to make.† His father forced a sweet smile and blessed his son. â€Å"I love you, son†, his father said and Greg just nodded. He hurriedly went to his car and drove like someone was chasing him. On his way, he felt sorry for his dad but at the same time, he felt excited that he will now be on his own. Arriving at Greg’s new place, he unhurriedly unpacked his things. A few minutes later, he discovered he has forgotten his documents at his father’s house. He is going to need them when he starts with his work so he has to return for it. He decided to fetch it the following day. Back at his father’s house, Greg found the place surprisingly quiet. He planned he will simply go to his room, retrieve what he needed and will not have to look for his father if he is not home. He noiselessly crept up the stairs then he heard a whimpering cry from the

Policy Choices Essay Example | Topics and Well Written Essays - 3000 words

Policy Choices - Essay Example Coming to an individual, what are the factors that influence actions of self interest Basically, individuals are goal oriented, and as such, they depend on their skills and resource to achieve their goals. Also, in order to achieve his goals, an individual may look for information, evaluate alternatives, and choose the ideal option. In the absence of these, there is manipulation due to lack of information and ignorance. There are also other factors involved in the process of decision making. "The rational ideal not only overstates the purity of information, it also exaggerates the rationality of the people using information. That humans do not make decisions in purely rational fashion is a point that needs no belaboring." [1] This is what Charles Lindblom has called "the preceptoral system," whereby "a system of social control is exercised by a highly unilateral governmental persuasion addressed not to an elite or to a bureaucracy alone but to an entire population" [2] "While the individual in the rational ideal is autonomous, free to deliberate and choose on the basis of accurate information, in the preceptoral system the individual is a puppet whose mind has been invaded by others and who acts as though he or she chooses voluntarily but is in fact directed from without." [3] The practice of restriction or suppression of information is not only confined to totalitarian regimes, it is also practiced in the highly scientific corridors of medical research, mega business houses, the media, law agencies, political parties, and at the highest levels of the proponents of free society. [4] Nonetheless, public-interest is the result of experience and proper understanding of what the problem is and how the solution could be achieved with minimum confusion and confrontation. It involves public debate and perception, and allows for discussion and information based solutions, instead of leaving it to the discretion of a single individual. "The rational ideal, in sum, offers a vision of society where conflict is temporary and unnecessary, where force is replaced by discussion, and where individual actions are 1Policy Paradox, p314. 2Policy Paradox, Chapter 13, page 316. 3Policy Paradox, p308. 4Why Public Ideas Matter Chapter 2, page 31 brought into harmony through the persuasive power of logic and evidence. Government by persuasion brings out the highest human quality - the capacity to deliberate." [5] However, the decision making process often tend to be long and tedious on issues related to public interest. That is why sometimes it is felt that that there is the need for some element of totalitarianism in government. That is to say, it is not always necessary for government to be of the totalitarian type in order to use persuasion. "Let us for the moment, however, not make totalitarian government a necessary condition for indoctrination and so not limit indoctrination to totalitarian regimes by definition. Instead, let us regard it as a relationship in which dominant elites control people's beliefs and

Rate Law and Activation Energy Essay Example for Free

Rate Law and Activation Energy Essay Introduction In this experiment we are analyzing the relationship between reaction rates at different concentrations and temperatures to determine the true rate constant, activation energy, reaction orders, and half-life of a reaction. The reaction of interest is the addition of a hydroxyl group to the nucleus of Crystal Violet. Crystal Violet, or hexamethylparaosaniline chloride for short, is a strongly colored purple dye with the chemical formula C25H30N3Cl and disassociates completely in solution. The relevant structure for this compound can be seen in figure 1 Figure 1 The base that is being used for the reaction is the strong base Sodium Hydroxide, or NaOH. This molecule also completely disassociates in water. Because measuring the concentrations of reactants is difficult in a simple lab setting, the reaction between Crystal Violet and Sodium Hydroxide will be measured through light absorbance. As the reaction between the chemicals takes place and the Crystal Violet receives the hydroxide the overall intensity of the purple color will decrease thus affecting the absorbance. The absorbance of the solution will be measured with a colorimeter as the reaction takes place and will be interpreted as a direct representation of concentration of Crystal Violet. After the reaction has taken place, through analysis of graphs plotting absorption vs. time, the natural log of absorption vs. time, and the inverse of absorption vs. time the reaction will be determined to be either zeroth, first, or second order with respect to crystal violet. From here the a pseudo rate constant can be determined, and using comparisons of different constants at different concentrations of NaOH solution and different temperatures, the reaction order with respect to hydroxide, the true rate constant for the reaction, and the activation energy for the reaction can all be determined with the following equations respectively. equation 1 Where k2’ is the pseudo rate constant of the reaction using twice the initial OH- concentration as is used in the k1’ reaction and n is equal to the reaction order with respect to OH-. equation 2 Where k’ is a pseudo rate constant based off of absorption and n is the reaction order with respect to OH- determined by equation 1. equation 3 Where k1 is the reaction constant at temperature T1, a is a constant that can be ignored due to the way the equation will be utilized, R is that gas constant, and Ea is the activation energy. Procedure The following materials were needed for the experiment: 4 100mL beakers 250mL beaker 2.5Ãâ€"10-5M Crystal Violet Stock solution 0.10M NaOH Stock solution Distilled Water 10 dry plastic cuvettes and caps Stirring rod Vernier Colorimeter 50mL volumetric pipet 100 µL syringe 2 10mL vials Logger Pro software Vernier computer interface Hot plate Vernier temperature probe 1. First, 100mL of 0.10M NaOH solution was obtained using a 50mL volumetric pipet, and 0.05M was prepared using a the pipet, the stock 0.10M NaOH solution, and distilled water. 2. The Logger Pro software was engaged and both the Vernier colorimeter and temperature probe were plugged into the appropriate channels. The temperature of the room was measured and the colorimeter was calibrated by setting the 0% light and 100% light conditions. 3. The colorimeter was set to 565nm and 1mL of 2.5Ãâ€"10-5M Crystal Violet solution was mixed with 1mL of 0.05M NaOH solution and quickly added to the colorimeter. Data correlating time, temperature, transmittance, and absorbance was then recorded for seven minutes as the reaction between the two solutions took place, and this data was saved. 4. This previous step was repeated two additional times with the 0.05M NaOH solution, and then three times with the 0.10M NaOH solution. 5. Last, two 10mL-vials of 0.05M NaOH and 2.5Ãâ€"10-5M Crystal Violet solution were prepared in a warm bath solution on the hot plate. Once the temperature reached 35ËšC and was recorded, steps BLANK through BLANK were repeated again twice with the heated solutions of Crystal Violet and 0.05M NaOH. All of the data that was collected was saved and distributed between the two lab partners and all excess solutions were disposed of properly under the fume hood. Results The following are the graphs obtained from the absorption and time recordings of the third run for the reaction between 1mL of 0.05M NaOH and 1mL of and 2.5Ãâ€"10-5M Crystal Violet carried out at 22.62ËšC. figure 2 figure 3 figure 4 These plots show that the reaction order with respect to crystal violet is clearly 1st order due to the great r2 value of the linear trend line. Since our pseudo rate constant based off of absorption is equal to the negative slope of our linear plot, our k’ in for the reaction of 1mL of 0.05M NaOH and 1mL of and 2.5Ãâ€"10-5M Crystal Violet carried out at 22.62ËšC is 0.1894. These next three plots are the graphs obtained from the absorption and time recordings of the first run for the reaction between 1mL of 0.10M NaOH and 1mL of and 2.5Ãâ€"10-5M Crystal Violet carried out at 22.50ËšC. figure 5 figure 6 figure 7 As expected, these results still indicate a reaction order of 1 with respect to crystal violet as demonstrated by the linear plot on the figure 6. Our k’ in for the reaction of 1mL of 0.10M NaOH and 1mL of and 2.5Ãâ€"10-5M Crystal Violet carried out at 22.50ËšC is 0.2993. Now that we have two pseudo reaction constants in which the OH- concentration differs by a factor of 2, we can use equation 1 to obtain the reaction order with respect to OH-. Since the reaction order must be an integer we can see that the n must be 1. It is now know that for the reaction, the reaction orders with respect to both reactants are 1. At this point, the true rate constant can be determined using equation 2, where n is 1, the initial concentration of OH- is 0.05, and the pseudo rate constant k’ is 0.1894. These next three plots are the graphs obtained from the absorption and time recordings of the first run for the reaction between 1mL of 0.05M NaOH and 1mL of and 2.5Ãâ€"10-5M Crystal Violet carried out at 36.09ËšC. figure 8 figure 9 figure 10 Once again it is apparent from the three plots that the reaction is first order with respect to crystal violet. However, the reason we performed this last kinetic run was to obtain a value for k at a different temperature. This way we have two sets of values for equation 3 with two temperatures, and two rate constants. With this information we can cut out the pre-exponential factor a and solve for the activation energy. But first k must again be calculated for the reaction at the new temperature. Doing this the same way as done in calculation 2, we obtain a reaction constant of 4.964 – a higher value, which is to be expected with the increase in temperature. Now, manipulating equation 4 we obtain that equation 4 While plugging the proper values provides which after some arithmetic leads to a calculated Ea of 15,254.67J, or 15.25467kJ. The calculation for half-lives for the different conditions is simple, and just requires the following equation. equation 5 When using the rate constant found in calculation 1, t1/2 for the kinetic run for the reaction between 1mL of 0.05M NaOH and 1mL of and 2.5Ãâ€"10-5M Crystal Violet carried out at 22.62ËšC is found to be 0.183 seconds. Error Analysis In this experiment there are several things calculated and several sources of error to take into account. Error needs to be calculated for the rate constants k, for the half-lives, and for activation energy. The errors for the pseudo-rate constants are obtained using the LLS method. Once these are obtained the next step is to calculate the error in the true rate constants. When calculating the error in true rate constant once must apply both the error in the pseudo rate constant and the error in the measurement of volume for the 100 µL syringe as it pertains to the concentration of hydroxide. The error in the syringe is 0.02mL, which for 0.05M NaOH solution leads to an error in concentration of approximately 1Ãâ€"10-3M and 2Ãâ€"10-3M for 0.10M NaOH. Equation 2 is manipulated to solve for the true rate constant. The following equation is used to solve for the error in the true rate constant. equation 6 And when the derivatives are solved is equal to equation 7 And when the numbers are plugged in for the first kinetic run looks like calculation =.08 In other words, the rate constant for the first kinetic run came out to be 3.79 ±.08. Now when calculating the error in the half-life the only thing that has to be taken into consideration is the error in the rate constant, which was just calculated above. Using the same method, equation 5 is solved for half-life, and the error is calculated like so. equation 8 Which after the derivatives are solved is equal to equation 9 And of course after the correct values for example the first kinetic run are plugged in provides calculation = .004 And last but nowhere near least, is the error analysis for the activation energy. With this the error for the true rate constant must again be taken into consideration, and the error for the temperature probe. The error for the true rate constant has already been calculated, while the error for the temperature probe is provided in the lab manual as being  ±0.03K. Taking these into consideration, a very complex process follows. The same process as above was used but involving much more complicated and lengthy derivatives. First equation 3 was manipulated to the following form. equation 10 The derivative of this equation with respect to each variable (T1, T2, K1, and K2) was then taken squared, and multiplied by the square of the respective variables uncertainty. These were added up and the square root was taken as in the above methods. The end result was a calculated error of 2 KJ for the calculated activation energy of 15kJ. Figure 11 Overall this lab was very successful in the use of absorption as a method of monitoring change in concentration. The calculated errors all seem to be about what one might expect. This lab was very analytical outside of one glaring hole. You can see in figure 9 a slight curve in the plot that isn’t found on either figure 3 or figure 6. To me this seems to be because the reactants are heated up to a temperature around 35-36ËšC, but once the chemicals are mixed and placed in the cuvette the temperature is no longer controlled as the reaction takes place for the following seven minutes. Thus, as the temperature falls the rate of the reaction slows, and the pseudo rate constant is lower than it should be. This of course leads to a rate constant lower than it should be, and then the activation energy is affected as well. If I were going to change one thing about the lab, I would try and do something to control the temperature as the reaction persisted. Aside from that, there is little room for error outside of obvious blunders. Conclusion A reasonable value for activation energy was calculated from the data collected in this experiment. There were no major mistakes made in the laboratory, and the calculations all went smoothly. This experiment demonstrated that there are creative ways around difficult problems in the laboratory, such as measuring absorption in place of concentration to follow the progress of a reaction.
