Chemical that increases the rate of a reaction but does not take a direct part in the reaction, so that it is still intact after the reaction has taken place. There are a number of factors that influence the rates of the chemical reactions, which includes the chemical essence of the reacting species and the outside factors they are exposed to. A specific occurrence related with the velocities of the chemical reactions, is the process of catalysis that points to the substances not consumed in the reactions during acceleration. Catalysis divulges into the basic nature of chemical reactions and is ultimately what many industrial processes rely upon for successful performance. Furthermore, it should be noted that life itself would not exist without organic catalysts called enzymes.
