化剂 是一种物质,它能够改变化学反应的速率,而不改变该反应的标准Gibbs自由焓变化,此过程称为催化作用,涉及催化剂的反应称为催化反应。 A catalyst is a substance that can change the rate of a chemical reaction without changing the standard Gibbs free enthalpy change of the reaction. This process is called catalysis, and reactions involving catalysts are called catalytic reactions.

Basic characteristics of the catalyst:

The catalyst can only achieve thermodynamically feasible reactions, not thermodynamically impossible reactions;

The catalyst can only change the speed of the chemical reaction, not the position of the chemical equilibrium;

The catalyst can reduce the activation energy of the reaction and change the course of the reaction;

The catalyst is selective for the reaction.
