The degree of dissociation ' α ' of the reaction N 2 O 4 g ⇌ 2 N O 2 g Can be related to K p as [Given: Total pressure at equilibrium = P)
Options
- Aα = K P P 4 + K P P
- Bα = K P 4 + K P
- Cα = K P / P 4 + K P / P 1 / 2
- Dα = K P 4 + K P 1 / 2
Correct answer
C. α = K P / P 4 + K P / P 1 / 2
Step-by-step solution
N 2 O 4 g ⇌ 2 N O 2 g K P = 2 α 2 1 – α × P 1 + α 1 K P = 4 α 2 1 – α 2 P α = K P / P 4 + K P / P 1 / 2
