Introduction
Catalyst lowers the activation energy for the forward and reverse reactions by exactly the same amount. Catalyst does not affect the equilibrium composition of a reaction mixture. It does not appear in the balanced chemical equation or in the equilibrium constant expression.
Pre-Requisites:
Reaction, equilibrium constant, reaction quotient, catalyst

| Le Chatelier’s principle | • Le Chatelier’s principle states that a “change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such a manner so as to restore the balance.” This is applicable to all physical and chemical equilibria. |
