Each equilibrium constant expression has a constant value ... The activities of pure solids and liquids are equal to 1 ... Here we have gases in contact with a solid
Pure solids and liquids are not included in the equilibrium constant expression. This is because they do notaffect the reactant amount at equilibrium in the reaction, so they are disregarded and kept at 1. Remember that the activity, a, of any solid or liquid in a reaction is equal to 1.

Explanation:
The concentrations of pure solids, pure liquids, and solvents are omitted from equilibrium constant expressions because they do not change significantly during reactions when enough is present to reach equilibrium.
