A 20 litre container at 400 K contains $CO_2(g)$ at pressure $0.4\; atm$ and an excess of $SrO$ (neglect the volume of solid $SrO$). The volume of the container is now decreased by moving the movable piston fitted in the container. The maximum volume of the container, when pressure of $CO_2$ attains its maximum value, will be : <br> (Given that : $SrCO_3 (s) \stackrel{K}\rightleftharpoons SrO (s) + CO_2 (g), Kp = 1.6 \; atm$ )
