Characteristics of Chemical Equilibrium

 The various characteristics of chemical equilibrium are:

(i).      The observable properties of the system become constant at equilibrium and remain unchanged thereafter. 

(ii).      The equilibrium is obtained only in the reactions carried in a closed vessels.

(iii).     The equilibrium is dynamic in nature.

(iv).     A catalyst cannot alter the equilibrium point.

(v).      The free energy change at equilibrium state is zero.
