Which of the following is true for a reversible reaction at equilibrium?

مندرجہ ذیل میں سے کون سا توازن پر الٹ جانے والے رد عمل کے لیے درست ہے؟
Explanation

At equilibrium, the rate of forward reaction is equal to the rate of backward reaction.

This is as per the definition of the equilibrium.

When a reversible reaction is carried out in a closed vessel, a stage is reached when the forward and the backward reactions proceed with the same speed.
