For the reaction N 2 O 4 ⇌ 2 N O 2 g , the degree of dissociation of N 2 O 4 is 0.2 at 1 a t m . Then the K p of 2 N O 2 ⇌ N 2 O 4 is

Correct answer

6

Step-by-step solution

K p = P NO 2 2 P N 2 O 4 K p = 4 α 2 1 − α 2 p ⇒ K p = 4 × 0.2 2 1 − 0.2 2 = 0.16 0.96 for 2 NO 2 ⇌ N 2 O 4 ; K p = 0.96 0.16 = 6
