Kinetics is the study of rates of chemical reactions. Kinetics allows the chemists to predict how the speed of a reaction will change under a reaction conditions. The study of kinetics is very important because it can elucidate the information about the mechanism of a reaction and can also allow chemists to be more efficient in the laboratory. At higher concentrations a reaction will proceed more quickly. In a step wise reaction, the rate determining step (RDS) is the step with the highest energy transition state, also known as slow step.
