Why equilibrium constant of a reaction does not change in the presence of a catalyst ?

The equilibrium constant of a reaction changes when

Why does equilibrium constant not change with the Presence of a catalyst ?

A : A catalyst does not alter the equilibrium constant of a reaction R : A catalyst does not alter the position of chemical equilibrium .

A : A catalyst does not alter the equilibrium constant of a reaction R : A catalyst does not alter the position of chemical equilibrium .

How does a catalyst enhance the rate of a chemical reaction? At a constant temperature, does the enthalpy of chemical reaction remain same or change in presence of a catalyst?

The equilibrium constant of a reaction and the standard Gibbs energy change of the reaction are related by the equation
