If a steady-state situation in which a reverse process is occurring has a corresponding forward process, at a rate which achieves an exact balance, it is said to be in dynamic equilibrium.

With regard to the pressure and volume of water sealed in an exhausted vessel at a constant temperature, a balanced state of constant change is possible in which molecules are constantly being exchanged between ice, water, and water vapour phases. By definition this balanced state of constant change is dynamic equilibrium.

Static equilibrium can refer to a steady-state situation with no dynamic forces acting on its potential energy in either reverse or forward processes. By definition, in a state of static equilibrium there is balance, but no change, disturbance or movement.
