For the reaction in equilibrium,

I. CO(g)+12O2(g)⇌CO2(g)\mathrm{CO}(g)+\frac{1}{2} \mathrm{O}_2(g) \rightleftharpoons \mathrm{CO}_2(g)

II. 2CO(g)+O2(g)⇌2CO2(g)2 \mathrm{CO}(g)+\mathrm{O}_2(g) \rightleftharpoons 2 \mathrm{CO}_2(g)

Correct option: C
K2=K12,ΔG2=2ΔG1K_2=K_1^2, \Delta G_2=2 \Delta G_1
Option C (K2=K12,ΔG2=2ΔG1K_2=K_1^2, \Delta G_2=2 \Delta G_1) is correct because doubling the reaction squares the equilibrium constant and doubles the free energy change.
