For the decomposition reaction CaCO

_3

(s) ⇌ CaO(s) + CO

_2

(g) at a certain temperature,

K_p = 1.0\,\text{atm}

. A sealed container at this temperature contains excess solid CaCO

_3

and CaO along with CO

_2

at a partial pressure of 0.80 atm. Predict how the system will respond, if at all, as it moves toward equilibrium, and briefly justify your answer.
