Document Summary

Catalyst substance that increases the rate of a chemical reaction without itself being consumed or changed in the overall reaction. A catalyst does not change the equilibrium constant, it does not change the amount of product formed during the reaction. It only changes the rate at which the product is formed. A catalyst can decrease g in one of three ways. The catalyzed and uncatalyzed reactions can follow can similar mechanism, with the catalyst providing a way to make the reactant less stable. The catalyzed and uncatalyzed reactions can follow a similar mechanism, with the catalyst providing a way to make the transition state more stable. A catalyst can completely change the mechanism of the reaction, providing an alternative pathway with a smaller g than that of the uncatalyzed reaction. Acid catalyst increases the rate of a reaction by donating a proton to a reactant. The acid increases the rates of both slow steps of the reaction.
