Kinetics

Definition

Kinetics refers to the study of the rates of chemical reactions and the factors that influence these rates. It encompasses how quickly reactants convert into products and is essential in understanding processes such as self-assembly and template-directed synthesis, where molecular interactions dictate how structures form over time. Kinetics helps in optimizing conditions to control the speed of these processes, leading to desired outcomes in nanotechnology applications.
