Re: solids and liquids
Molar concentration of a pure substance (solid or liquid) does not change in a reaction, so solids and liquids are not included in the K expression

Re: solids and liquids [ENDORSED]
Solids and liquids are pure substances, so their concentrations do not change during the duration of the reaction,. Therefore solids and liquids are negligible when calculating Kc, Kp, and Q since they won't have any influence on the final answer to the equilibrium problems.

Re: solids and liquids
Molarity of a solid and liquid cannot change during the course of a reaction so there is no need to include them when finding K.

Re: solids and liquids
The nature of pure solids and liquids further can be extended to pure, inert gases (group VIII). Inert gas can be added to an equilibrium mixture at a constant volume to increase the pressure of the mixture; however there will be no change in equilibrium as the amount of neither reactant nor product is affected.
