The study of how quickly chemical reactions progress from reactants to products is known as chemical kinetics. The rate of a chemical reaction is described by chemical kinetics. This is the rate at which the reactants and products are changed. Chemical kinetics is the study of reaction rates in order to infer kinetic mechanisms for the chemical conversion of reactants (R) into products (P). A chemical reaction's rate is normally measured in seconds, however kinetics tests might last minutes, hours, or even days.
Catalytic activity is defined as the increase in the rate of a chemical reaction generated by an enzyme or other catalyst under certain test conditions. Katals or moles per second are the units of measurement. The nature of the support has a significant impact on the catalyst activity and reaction process.
