Dear anuj,


For unit concentration of reactants rate of the reaction is equal to rate constant or specific reaction rate.


            At equilibrium the rate of both forward and backward reactions become equal and after achieving equilibria, the concentration of reactants and products remains constant as shown in figure.


                        1053_forward and backward reactions.JPG




         Active mass is the molar concentration of the reacting substances actually participating in the reaction.


Hence

            Active mass = number of moles/volume in litres


            and Active mass of solid is taken as unity.
