A 20 L container at high temperature contains CO at pressure 0 4 atm and an excess of CaO s The volume of the container is now decreased by moving the movable piston fitted in the container The maximum value of volume of the container when pressure of CO attains its maximum value is found to be 4 L Kp of following equilibrium is CaCO3 s CaO s CO g A B C D 5 atm 10 atm 4 atm 2 atm
