Question

Which of the following is not a characteristic property of chemical equilibrium ? (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) leftharpoons B(g), Kc is 10-2. If this reaction is carried out in the presence of catalyst, the value of Kc decreases (D) After reaching the equilibrium, both forward and backward reactions continue to take place

There will be no effect on equilibrium constant (Kc) in presence of catalyst.

Q. Which of the following is not a characteristic property of chemical equilibrium ?

Rate of forward reaction is equal to rate of backward reaction at equilibrium.

After reaching the chemical equilibrium, the concentrations of reactants and products remain unchanged with time.

For $A (g) ⇌ B (g), K_{c}$ is $1 0^{- 2}$ . If this reaction is carried out in the presence of catalyst, the value of $K_{c}$ decreases

After reaching the equilibrium, both forward and backward reactions continue to take place

There will be no effect on equilibrium constant $(K_{c})$ in presence of catalyst.
