Question

One mole of a compound AB reacts with one mole of  a compound CD according to the equation $$AB(g)+CD(g)$$⇌$$AD(g)+CB(g)$$      . When  equilibrium had been established it was found that $$3/4$$ mole of reactants AB  and CD had been converted to AD and CB. There is no change in volume. The  equilibrium constant for the reaction is
