solids and liquids

why are solids and liquids not included in the equilibrium constant equation?

Solids and liquids are not included in the equilibrium constant because their concentrations stay constant throughout the entire reaction

I think it is because their concentrations do not change throughout the reaction and do not affect the concentrations at equilibrium. As the density of a pure solid or liquid remains the same no matter what volume, the concentration is also the same.

Solids and liquids (pure substances) are not included in the K expression because the molar concentration does not change in a reaction.
