In a reversible chemical reaction (where, Δx = number of moles of products-number of moles of reactants)
(A) Addition of inert gas favours the forward reaction, when Δx is positive
(B) Pressure has no effect on equilibrium, when Δn = 0
(C) Addition of inert gas has no effect on the equilibrium constant at constant volume for any value of Δx (+ ve, - ve) or zero)
(D) All 'a', 'b' & 'c'
