Which statement correctly defines dynamic equilibrium?

a) at dynamic equilibrium, the rates of forward and reverse reactions are equal.
b) at dynamic equilibrium, the rate of the forward reaction is higher than the rate of the reverse reaction.
c) at dynamic equilibrium, the forward and reverse reactions stop.
d) at dynamic equilibrium, the concentrations of reactants and products are equal.

Answer : The correct option is, (A) At dynamic equilibrium, the rates of forward and reverse reactions are equal.

Explanation :

As we know that the equilibrium is the state in a chemical reaction at which the rate of forward reaction is equal to the rate of backward reaction.

Dynamic equilibrium : It is defined as the state at which the rate of forward reaction always be equal to the rate of reverse reaction.

Or we can say that, at the dynamic equilibrium the reactants are converted to the products and the products are converted to the reactants at equal and constant rate.

Hence, the correct option is, (A) At dynamic equilibrium, the rates of forward and reverse reactions are equal.
