The characteristics which do not represent chemical equilibrium are :(A) ΔG=0 (B) the properties of the system are time dependent.(C) the rates of the forward and backward reactions are equal. (D) the concentrations of reactants and products are equal always.The correct answer is

For equilibrium reactions $Δ G = 0$ and rates of forward and backward reactions are equal (1), (3) are correct.

At equilibrium, the properties do not change with time. So (2) is incorrect.

The concentrations of products and reactants are equal only when $K_{c} = 1$ So (4) is incorrect.

The characteristics which do not represent chemical equilibrium are :
(A) $ΔG = 0$
(B) the properties of the system are time dependent.
(C) the rates of the forward and backward reactions are equal.
(D) the concentrations of reactants and products are equal always.
The correct answer is
