NEETChemistryChemical EquilibriumMCQ+4 / −1
If the equilibrium constant for

N2(g) + O2(g) ⇌\rightleftharpoons⇌ 2NO(g) is K, the equilibrium

constant for

12{1 \over 2}21​ N2(g) + 12{1 \over 2}21​O2(g) ⇌\rightleftharpoons⇌ NO(g) will be
  1. A
    12{1 \over 2}21​ K
  2. B
    K
  3. C
    K2
  4. D
    K1/2

Correct answer: D

When a reaction is divided by factor n then the new equilibrium constant of the reaction will be Kn\sqrt[n]K nK​ .

Thus, here the given reaction is multiplied by factor 12{1 \over 2}21​ then the new equilibrium constant will be K12{K^{{1 \over 2}}}K21​ .
