Book excerpt: This book gathers perspectives, applications, and developments in the extensively researched fields of chemical kinetics and catalysis. Catalysis is a key component of modern industry advancements ranging from production to energy and environmental sustainability, and chemical kinetics offers important information about a reaction. In addition to discussing redox processes, kinetics, and density functional theory, this book bridges the gap between the worlds of enzymes and electric fields and focuses on the shortcomings of transition state theory (TST).
