Kinetics is the branch of science that studies the rates of chemical reactions and the factors that influence them. It helps us understand how quickly reactants turn into products and what conditions, such as temperature and concentration, can speed up or slow down these processes. In addition to chemistry, kinetics is also important in fields like physics and biochemistry. For example, in physics, it examines the motion of objects and the forces acting on them. In biochemistry, it looks at how enzymes affect the speed of biological reactions, which is crucial for understanding metabolism and cellular functions.
