Assertion : The dissociation of CaCO3 can be represented as, CaCO3(s) \(\text { ⇌ }\)CaO(s) + CO2(g). Some solid CaCO3 is placed in an evacuated vessel enclosed by a piston and heated so that a portion of it is decomposed. If the piston is moved so that the volume of the vessel is doubled, while the temperature is held constant, the number of moles of CO2 in the vessel increases.
Reason : The pressure of CO2 in the vessel will remain the same.
Reason : The pressure of CO2 in the vessel will remain the same.
