In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. For the overall system to be in equilibrium, the chemical potential of the compound in each phase present must be the same. Equilibrium is defined as a stage when the chemical potential of any component present in the system stays steady with time.
