Question 240 of 246

A 10L container at 300K contains CO2 gas at pressure of 0.2 atm and an excess solid CaO (neglect thevolume of solid CaO). The volume of container is now decreased by moving the movable piston fitted in the container. What will be the maximum volume of container when pressure of CO2 attains its maximum value given that CaCO3 (s) CaO(s) + CO2(g)Kph = 0.800 atm

(1) 5 L

(2) 2.5 L

(3) 1 L

(4) The information is insufficient.
