dynamic equilibrium

A dynamic equilibrium occurs when two reversible processes proceed at the same rate. Many processes (such as some chemical reactions) are reversible and when at dynamic equilibrium the forward reaction will occur at the same rate as the reverse reaction such that there is no further change in concentration of reactants or products.

Compare with position of equilibrium .Dynamic equilibrium is established when two opposing processes are occuring at precisely the same rate, so that there is no apparent change in the system over long periods of time.
