Consider two vessels X and Y , each of volume V, and at temperature T , connected through a tube fitted with a stop cock. Vessel X initially contains 1 mole of A ( s ) , which establishes the equilibrium A ( s ) B ( g ) leading to the gas pressure P . In vessel Y there is vacuum. The stop cock is then opened and new equilibrium is allowed to be established at constant temperature. The pressure observed in both the ve
