- Reversible reactions are the reactions which do not go to completion and occur in both the directions simultaneously.
- If such a reaction is allowed to take place for a long time, so that the concentrations of the reactants and products do not vary with time, then the reaction will attain equilibrium.
- Since, both the forward and backward reactions continue to take place in opposite directions in the same speed, the equilibrium achieved is dynamic in nature.
Thus,
If the reaction is not reversible then it cannot attain dynamic equilibrium.
