For the reversible reaction

\mathrm{CaCO_3(s) \rightleftharpoons CaO(s) + CO_2(g)}

at a given temperature,

K_c = 0.20

. A sealed container initially has

[\mathrm{CO_2}] = 0.50\,\mathrm{M}

in the presence of solid

\mathrm{CaCO_3}

and solid

\mathrm{CaO}

, and the system is not at equilibrium. (Solids are not included in

Q_c

.) Based on comparing

Q_c

and

K_c

, in which direction will the reaction proceed to reach equilibrium?
