The SI unit for catalysis is the katal. This is a derived unit which is moles per second. When enzymes catalyze a reaction, the preferred unit is the enzyme unit. The effectiveness of a catalyst may be expressed using the turnover number (TON) or turnover frequency (TOF), which is TON per unit time. Catalysis is a vital process in the chemical industry. It is estimated that 90% of commercially produced chemicals are synthesized via catalytic process. Sometimes the term "catalysis" is used to refer to a reaction in which a substance is consumed (e.g., base-catalyzed ester hydrolysis). According to the IUPAC, this is an incorrect usage of the term. In this situation, the substance added to the reaction should be called an activator instead of a catalyst. A catalyst offers a special transition state for a reaction, with a lower energy of activation. Collisions between reactant molecules are more likely to achieve the energy required to form products than without the presence of the catalyst. In some cases, one effect of catalysis is to lower the temperature at which a reaction will process. Catalysis does not change chemical equilibrium because it affects both the forward and reverse rate of reaction. It does not change the equilibrium constant. Similarly, the theoretical yield of a reaction is not affected.
