Question

Quizplus · Accepted Answer

Equilibrium constant expressions only include concentrations of reactants and products in solution or gas phase. The concentrations of pure solids and pure liquids do not change during a reaction and are not included in the expression. The concentrations of catalysts are also not included as they only speed up the rate of reaction and do not affect the equilibrium position. Only the concentrations of reactants and products in gas phase are included in the equilibrium constant expression.
