Question

Why equilibrium constant does not contain pure solids and liquids

Answer 1

The activities of pure solids and liquids are equal to 1. Pure solids and liquids are not included in theequilibrium constant expression. Thisis because they do not affect the reactant amount at equilibrium in the reaction, so they are disregarded and kept at 1

Answer 2
