Catalytic reaction kinetics focuses on understanding how catalysts influence the rate and mechanism of chemical reactions. Unlike non-catalyzed reactions, catalytic processes involve the participation of a catalyst that accelerates the reaction by lowering the activation energy without undergoing permanent chemical change. The kinetics of these reactions are crucial in determining the reaction rate, selectivity, and efficiency, especially in industrial and environmental applications. Key parameters include the reaction order, rate constants, activation energy, and the nature of the catalytic surface. For heterogeneous catalysis, factors such as surface area, pore size, and adsorption-desorption phenomena play a critical role in determining the reaction pathway and speed. In contrast, homogeneous catalysis often depends on the molecular interaction between the catalyst and reactants in the same phase.

Modeling the kinetics of catalytic reactions involves constructing rate laws that incorporate elementary reaction steps and intermediate species. These models are validated through experimental data and are vital in designing reactors, scaling up processes, and optimizing operating conditions. Techniques such as Langmuir-Hinshelwood and Eley-Rideal mechanisms are widely used to describe surface reactions in heterogeneous catalysis. Understanding catalytic kinetics also aids in identifying catalyst deactivation pathways and improving catalyst lifetime. With the advent of advanced computational tools and in-situ characterization techniques, researchers can now analyze catalytic processes at the atomic level, providing deeper insights into reaction mechanisms. Ultimately, mastering catalytic reaction kinetics is fundamental to the development of sustainable technologies in energy conversion, pharmaceuticals, and materials synthesis.
