Chemical Kinetics and Catalysis

Chemical kinetics is the study of the rates at which chemical reactions occur, the factors that influence these rates (such as concentration, temperature, and pressure), and the step-by-step molecular pathways, or mechanisms, by which reactants are converted into products. Closely related is the field of catalysis, which focuses on the action of catalysts—substances that increase the rate of a chemical reaction by providing an alternative pathway with a lower activation energy, without being consumed in the overall process. Together, these fields provide a dynamic picture of how and how fast chemical changes happen, forming the basis for controlling reactions in industrial processes, environmental systems, and biological organisms.
