The equilibrium-constant expression for heterogeneous equilibria
Heterogeneous equilibria involve reactants and products that are not all in the same phase. For example, a solid may decompose, forming two gases. When writing equilibrium-constant expressions for heterogeneous reactions,
generally the concentrations of pure solids and liquids are omitted. The composition of a pure solid or liquid does not change over the course of the reaction; only its quantity changes. Since its concentration isn't changing, the
values can usually be excluded.
Given the equation 2CD(s)=cC(g) + dD(g), the equilibrium constant expression would be
