WebNov 13, 2024 · The catalyst has no effect on the equilibrium constant or the direction of the reaction. The direction can be controlled by adding or removing water (Le Chatelier principle). Catalysts function by allowing the reaction to take place through an alternative mechanism that requires a smaller activation energy. WebCatalysts are defined as substances that participate in a chemical reaction but are not changed or consumed. Instead they provide a new mechanism for a reaction to occur which has a lower activation energy than that of the reaction without the catalyst.
