Q. Equilibrium constants K₁ and K₂ for the following equilibria : NO(g) + ½O₂(g) ⇌ NO₂(g) and 2NO₂(g) ⇌ 2NO(g) + O₂(g) are related as :
A) K₂ = 1/K₁
B) K₂ = K₁²
C) K₂ = K₁/2
D) K₂ = 1/K₁²
Explanation
[Solution from source] The second equilibrium is the first reversed and doubled. Reversing gives 1/K₁ and doubling squares it, so K₂ = 1/K₁². 1/K₁ forgets the factor of 2. Answer (4).
