Question

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?

Answer 1

Kp of the reaction is 0.0215

Step-by-step 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
