Re: solids and liquids
Since solids and liquids cannot affect the reaction at equilibrium they are not included in the equilibrium expression.

Re: solids and liquids
Solids and liquids are pure and they don't affect the reactant amount so they are omitted from the equilibrium expression. Also, the concentrations of these pure solids and liquids are calculated by dividing their density by molar mass and their density remains constant regardless of the amount of pure solid or liquid so it will not affect the equilibrium expression.

Re: solids and liquids
Solids and liquids don't affect the reactant amount at equilibrium. They don't change in concentration (solids don't really even have "concentrations") so they're not included.

Re: solids and liquids
Solids and liquids are not included in the K calculation because K is calculated using concentrations. Solids and liquids do not have concentrations, so they cannot affect the equilibrium.

Re: solids and liquids
solids and liquids aren't included in the equilibrium equation because the molar concentration of a pure substance (liquid or solid) does not change in a reaction.
