Consider the reactions 1 2 N 2 + O 2 ⇌ N O 2 K 1 2 N O 2 ⇌ N 2 O 4 K 2 Using above equations, write down expression for K of the following reaction N 2 O 4 ⇌ N 2 + 2 O 2 K

Options

  1. AK 1 K 2
  2. BK 2 2 K 1
  3. C1 K 1 K 2 2
  4. D1 K 1 2 K 2

Correct answer

D. 1 K 1 2 K 2

Step-by-step solution

K 1 = [ N O 2 ] [ N 2 ] 1 / 2 [ O 2 ] …(i) K 2 = [ N 2 O 4 ] [ N O 2 ] 2 …(ii) K = [ N 2 ] [ O 2 ] 2 [ N 2 O 4 ] …(iii) Considering equation (i), (ii) and (iii) K = 1 K 1 2 K 2 .
