statement-1 :The dissociatiohn of CaCO_(3) can be represented as, CaCO_(3)(s)hArrCaO(s)+CO_(2)(g). Some solid CaCO_(3) is placed in an evacurted vessel enclosed by a piston and heated so that a portion of it decomposes. If the piston is moved so that the volume of the vessel is doubled, while the tempratuere is held constant, the number moles of CO_(2) in the vessel increase. statement-2 : The pressure of CO_(2) in the vessel will remain the same.
