(D) For a heterogeneous equilibrium reaction involving solids and gases,the concentration or partial pressure of pure solids is taken as unity $(1)$.Given the reaction: $ZnCO_{3(s)} \rightleftharpoons ZnO_{(s)} + CO_{2(g)}$.The equilibrium constant expression in terms of partial pressure is $K_p = \frac{P_{ZnO} \times P_{CO_2}}{P_{ZnCO_3}}$.Since $ZnCO_{3(s)}$ and $ZnO_{(s)}$ are pure solids,their partial pressures are considered as $1$.Therefore,$K_p = 1 \times P_{CO_2} / 1 = P_{CO_2}$.
