WebFor gas-phase solutions, the equilibrium constant may be expressed in terms of either the molar concentrations ( Kc) or partial pressures ( Kp) of the reactants and products. A relation between these two K values may be simply derived from the ideal gas equation and the definition of molarity: PV = nRT P = (n V)RT = MRT WebApr 5, 2024 · Solution: Given the reversible equation, H2 + I2 ⇌ 2 HI. The change in the number of moles of gas molecules for the given equation is, ⇒ Δn = number of moles of product - number of moles of reactant. ⇒ Δn = 2 - 2 = 0. Therefore, Kp = Kc. Then, Kp and Kc of the equation is calculated as follows, k c = H I 2 H 2 I 2.
