Vedclass · Answer

(C) catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
It works by providing an alternative reaction pathway with a lower activation energy.
However,a catalyst does not alter the Gibbs free energy change $(\Delta G)$ of the reaction,nor does it change the equilibrium constant of the reaction.
