Transition state theory (TST), also known as activated complex theory, is a theoretical framework in chemical kinetics that describes the rates of chemical reactions. The main idea behind this theory is that during a reaction, reactants must pass through a high-energy state called the "transition state" or "activated complex" before transforming into products.
