The equilibrium constant for the reaction N_2(~g)+O_2(~g)...

The equilibrium constant for the reaction N2( g)+O2( g)⇌2NO(g)\mathrm{N}_2(\mathrm{~g})+\mathrm{O}_2(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}(\mathrm{g}) at temperature T\mathrm{T} is 4×10−44 \times 10^{-4}. The value of Kc\mathrm{Kc} for the reaction NO(g)⇌12 N2( g)+12O2( g)\mathrm{NO}(\mathrm{g}) \rightleftharpoons \frac{1}{2} \mathrm{~N}_2(\mathrm{~g})+\frac{1}{2} \mathrm{O}_2(\mathrm{~g}) at the same temperature is
