Statements that are always true for a reaction at equilibrium are : a) the rate of the forward and reverse reactions are equal ; and b)the concentrations of the reactants and the products remain constant.
A system is said to be at equilibrium when the rates of the forward and reverse reactions are equal. If additional reactant is added then the rate of the forward reaction increases. As the rate of the reverse reaction is initially not changed then the equilibrium shifts towards the product.
The reaction rates of the forward and backward reactions are not zero but they are equal. Therefore, there is no net changes in the concentrations of the reactant and product which is known as dynamic equilibrium.
