The equilibrium constants of the following are: N 2 + 3 H 2 ⇌ 2   NH 3 K 1 N 2 + O 2 ⇌ 2   NO K 2 H 2 + 1 2 O 2 → H 2 O   K 3 The equilibrium constant ( K ) of the reaction: 2 N ⁡ H ⁡ 3 + 5 2 O ⁡ 2 ⇌ K ⁡ 2 N ⁡ O ⁡ + 3 H ⁡ 2 O ⁡ , will be:

Options

  1. AK 1   K 3 3 K 2
  2. BK 2   K 3 3 K 1
  3. CK 2   K 3 K 1
  4. DK 2 3   K 3 K 1

Correct answer

B. K 2   K 3 3 K 1

Step-by-step solution

(I) N 2 + 3 H 2 ⇌ 2 NH 3 ;   K 1 = NH 3 2 N 2    H 2 3 (II) N 2 + O 2 ⇌ 2 NO ;   K 2 = NO 2 N 2   O 2 (III) H 2 + 1 2 O 2 → H 2 O ;   K 3 = H 2 O H 2   O 2 1 2 II + 3 × III - I will give 2 N ⁡ H ⁡ 3 + 5 2 O ⁡ 2 ⇌ K ⁡ 2 N ⁡ O ⁡ + 3 H ⁡ 2 O ⁡ ; ∴         K = K 2 × K 3 3 K 1
