Kinetics is the branch of physical chemistry that studies the rates of chemical reactions and the factors that influence those rates. It involves measuring and analyzing the speed at which chemical reactions occur, as well as understanding the underlying mechanisms that govern these reactions. Kinetics aims to answer questions such as how fast a reaction proceeds, what factors affect the reaction rate, and how reactions can be controlled or optimized. This field plays a crucial role in various industries, such as pharmaceuticals, materials science, and environmental science, by providing valuable information for the design and optimization of chemical processes.
