Chemistry - Chemical Equilibrium Question with Solution | TestHub

A 10 L container at 300 K contains ${\mathrm{CO}}_2$ gas at pressure of 0.2 atm and an excess solid CaO (neglect the volume 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 ${\mathrm{CO}}_2$ attains its maximum value given that ${\mathrm{CaCO}}_3(\mathrm{s})\rightleftharpoons \mathrm{CaO}(\mathrm{s})+{\mathrm{CO}}_2(\mathrm{g});{\mathrm{K}}_{\mathrm{p}}=0.800\mathrm{atm}$
