Consider the following reversible chemical reactions: A 2 g + B 2 g ⇌ k 1 2 A B g .....(1) 6 A B g ⇌ k 2 3 A 2 g + 3 B 2 g .....(2) The relation between K 1 and K 2 is:

Options

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

Correct answer

A. K 2 = K 1 - 3

Step-by-step solution

A 2 + B 2 ⇌ 2 A B k 1 = A B 2 A 2 B 2 6 A B ⇌ 3 A 2 + 3 B 2 k 2 = A 2 3 B 2 3 A B 6 So, 1 k 1 3 = k 2
