If there is no change in concentration, why is the equilibrium state considered dynamic ?

Text Solution

Verified by Experts

Chemical reactions which are reversible do not cease, when equilibrium is attained. At equilibrium the forward and the backward reactions are proceeding at the same rate and no macroscopic change is observed. So chemical equilibrium is in a state of dynamic equilibrium.
