Summary: catalysis in Brief

Catalysis [kəˈtaləsɪs] refers to the acceleration or deceleration of a chemical reaction through a catalyst. It is used in various fields, including industrial chemistry and biochemistry, and can be classified into homogeneous and heterogeneous catalysis. Examples include the use of enzymes as biological catalysts and the production of ammonia from nitrogen and hydrogen. The term 'catalysis' is formal and synonymous with 'acceleration' and 'stimulation.'
