Consider the reaction

N2 (g) + O2 (g) ⇌ 2NO (g)

If the equilibrium partial pressures of N2, O2, and NO are 0.22, 0.19, and 0.030 atm, respectively, at 2200°C, what is KP?

    Kp of the reaction is 0.0215

    Explanation:

    Step 1: Data given

    Partial pressure at the equilibrium of N2 = 0.22 atm

    Partial pressure at the equilibrium of O2 = 0.19 atm

    Partial pressure at the equilibrium of NO = 0.030 atm

    Temperature = 2200 °C

    Step 2: The balanced equation

    N2 (g) + O2 (g) ⇌ 2NO (g)

    Step 3: Calculate Kp

    Kp = (pNO) ² / (pO2) * (pN2)

    Kp = (0.030) ² / (0.19*0.22)

    Kp = 0.0215

    Kp of the reaction is 0.0215
