A reversible reaction achieves equilibrium when the rates of forward and backward reactions equal. At equilibrium, the ratio of product of molar concentrations of prodcuts and the prodcut of molar concentration of reactants each raised to the powers equal to their stoichiometric coefficients, becomes constant. In case of gaseous reactios, the partial pressure of gases may be used in place of their molar concentrations. If 1 mole of PCI_(5)(g) and 1 mole of CI_(2)(g) is taken in a 10L vessel, then the equilibrium concentration of PCI_(3)(g) will be : PCI_(3)(g)+CI_(2)(g)hArrPCI_(5)(g),""K_(c)=(20)/(3)M^(-1)
