The equilibrium constant of the following are reactions N 2 + 3 H 2 ⇌ 2 N H 3 K 1 N 2 + O 2 ⇌ 2 N O K 2 H 2 + 1 2 O 2 → H 2 O K 3 The equilibrium constant (K) of the reaction N H 3 + 5 2 O 2 ↔ K 2 N O + 3 H 2 O , will be

Options

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

Correct answer

A. K 2 K 3 3 / K 1

Step-by-step solution

N 2 + 3 H 2 ⇌ 2 N H 3 K 1 Reverse it. N 2 + O 2 ⇌ 2 N O K 2 H 2 + 1 2 O 2 → H 2 O K 3 × 3 2 N H 3 + 5 2 O 2 ⇌ 2 N O + 3 H 2 O K C K C = K 2 K 3 3 K 1
