WebApr 5, 2024 · Kc is the equilibrium constant given as a ratio between concentrations of products and reactants. Kp is the equilibrium constant given as a ratio between the pressure of products and reactants. Kc can be used for gaseous or liquid reaction mixtures. Kp is used only for gaseous reaction mixtures. Kc is given by units of concentration. 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.
