Which of the following is not the characteristic of chemical equilibrium ?

Options

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) rarr 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

Answer

C

Explanation

Catalyst does not alter the value of equilibrium constant
