Chemical kinetics is a branch of physical chemistry that analyzes the rate of reaction in each elemental stage as well as the catalytic mechanism that governs it. Molecular reaction dynamics, catalytic dynamics, elemental reaction dynamics, macrodynamics, and microdynamics are mainly included in it. The catalyst volume, surface, or mass can all influence the catalytic reaction rate. Furthermore, rates are frequently denoted as per volume of reactor in practical applications. In heterogeneous catalysis, such a study field has numerous applications. Chemical kinetics has advanced at a breakneck pace in recent years, with the confined fields gradually expanding as the study mode progressed from the basement state to the excitation state, from small molecules to large molecules, and from the gas phase to the condensed phase.
