  4. Statement 1: The dissociation of CaCO3 can be represented as, CaCO3(s)leftharpoons 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 decomposes. 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 increase Statement 2: The pressure of CO2 in the vessel will remain the same.

Q. Statement 1: The dissociation of $CaCO_3$ can be represented as, $CaCO_3\left(s\right)\rightleftharpoons CaO\left(s\right) + CO_2\left(g\right)$. Some solid $CaCO_3$ is placed in an evacuated 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 temperature is held constant, the number of moles of $CO_2$ in the vessel increase
Statement 2: The pressure of $CO_2$ in the vessel will remain the same.

Equilibrium

Solution:

Both statements are true and the statement 2 is the correct explanation of the statement 1.
