Heterogeneous Catalysis: Kinetics and Mechanisms

This lecture covers the fundamental concepts of heterogeneous catalysis, including the analysis of reaction mechanisms and kinetics. Topics include adsorption, reaction steps, desorption effects, and the role of reactive intermediates. The instructor presents a detailed overview of the ammonia synthesis reaction, emphasizing the importance of understanding rate-determining steps and the steady-state approximation. The lecture also discusses general rules for deriving rate equations in catalytic reactions, focusing on the significance of the most abundant reaction intermediate (MARI) and the simplification of reaction mechanisms. Through a series of problem sets and theoretical explanations, students gain insights into the complex processes involved in heterogeneous catalysis.
