Answer» Solution :(A)`Deltan_(g)` is +ve so as P is increased, BACKWARD shifting will take PLACE.Total pressure EVEN after shifting will remain same. (B)`Deltan_g` is -ve so as V is increased, backward shifting will take place. But `P_("final")ltP_("Initial")` ( C)No change but `P_("final")ltP_("Initial")` as volume has increased. (D)Forward shifting will take place and `P_("final")ltP_("Initial")`
