Answer» system is present in equilibrium when the quantities of the chemical substances involved do not change unless external factors like temperature, composition of the substances and pressure of the system is changed. At this point the chemical equilibrium is said to be stable. If there is a possibility that the composition at the equilibrium may change, but the rate of change is infinitesimally slow, the system is said to be in ametastablestate and it will havehigher free energy than the actual equilibrium state. |
