Introduction This chapter introduces the principles of chemical kinetics,the study of reaction rates,by showing how the rates of reactions may be measured and interpreted. The rate of a chemical reaction might depend on variables under our control,such as the pressure,the temperature,and the presence of a catalyst,and we may be able to optimize the rate by the appropriate choice of conditions. The study of reaction rates also leads to an understanding of the mechanisms of reactions,their analysis into a sequence of elementary steps PDF文件使用"pdfFactory Pro”试用版本创建w.fineprint.com.cn

Why do some reactions take place very rapidly (less than millionths of a second)while some reactions take years to occur? Why can changing the concentration(s)of reactants often change the rate with which they react? Why does temperature have such a dramatic effect on chemical reactions? Why do catalysts speed up some reactions but have little or no effect on other reactions? PDF文件使用"pdfFactory Pro”试用版本创建m,fineprint.com,cn
