What is the relationship between the equilibrium partial pressure and the equilibrium constant Kp in a chemical reaction?

The equilibrium partial pressure of gases in a chemical reaction is directly related to the equilibrium constant Kp. The equilibrium constant Kp is a measure of the ratio of the concentrations of products to reactants at equilibrium, and it is determined by the stoichiometry of the reaction. The equilibrium partial pressure of a gas is related to the concentrations of the gases in the reaction through the ideal gas law. The relationship between the equilibrium partial pressure and the equilibrium constant Kp is given by the expression: Kp (P(products)m) / (P(reactants)n), where m and n are the coefficients of the products and reactants in the balanced chemical equation.
