They will not necessarily be equal, but they will be constant.
In reversible reactions, dynamic equilibrium refers to a state in which the rate of the forward reaction is equal to that of the backward reaction.
Consdier the reaction below: A + B --> C + D
If the reaction is in dynamic equilibrium, the rate of formation of A and B will be the same as the rate of formation of C and D. However, this does not mean that the concentrations of the reactants and the products will be the same.
Since the rate of forward and backward reactions are equal, it means that the concentration of each of the species will be constant.
Thus, the above reaction is applicable to that of two reacting gases placed in a sealed flask and allowed to reach a dynamic equilibrium.
