For $A_{(g)} \rightleftharpoons B_{(g)}$,$K_c$ is $10^{-2}$. If this reaction is carried out in the presence of catalyst,the value of $K_c$ decreases.

(C) catalyst increases the rate of both forward and backward reactions equally,allowing the system to reach equilibrium faster. It does not change the position of equilibrium or the value of the equilibrium constant $(K_c)$. Therefore,the statement in option $(c)$ is incorrect.

A
Rate of forward reaction is equal to rate of backward reaction at equilibrium.
B
After reaching the chemical equilibrium,the concentrations of reactants and products remain unchanged with time.
C
For $A_{(g)} \rightleftharpoons B_{(g)}$,$K_c$ is $10^{-2}$. If this reaction is carried out in the presence of catalyst,the value of $K_c$ decreases.
D
After reaching the equilibrium,both forward and backward reactions continue to take place.
