The kinetics of chemical reactions is the part of chemistry that deals with the study of the speed with which reactions take place ( i ), one of the most important issues in any chemical process. Knowledge of reaction rates is important not only for its own sake, but also for the chemical industry, for understanding life-important biochemical processes, and in other fields of application. Therefore, we must define what is the speed with which a reaction takes place and learn to measure it, as well as discover what relationships exist between the speed of reactions and chemical equilibrium. But above all, we must know how the reactions take place and what are the microscopic processes that correspond to the changes in the chemical species. Since most reactions occur through molecular collisions of some kind, it is important to also study the nature of these collisions, and chemical kinetics is involved in that study.
