Equilibrium concentrations are unchanged

(C) catalyst provides an alternative pathway with lower activation energy for both the forward and backward reactions. It increases the rate of both reactions to the same extent. Therefore,the equilibrium position and the equilibrium concentrations remain unchanged. Also,the equilibrium constant $(K_{eq})$ depends only on temperature and is not affected by the presence of a catalyst.
