Chemistry - Chemical Equilibrium Question with Solution | TestHub

The equilibrium constant $\left({\mathrm{K}}_{\mathrm{c}}\right)$ for the reaction ${\mathrm{N}}_2(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})\to 2\mathrm{NO}(\mathrm{g})$ at temperature $\mathrm{T}$ is $4\times 10^{-4}$. The value of ${\mathrm{K}}_{\mathrm{c}}$ for the reaction, $\mathrm{NO}(\mathrm{g})\to 1/2{\mathrm{N}}_2(\mathrm{g})+1/2{\mathrm{O}}_2(\mathrm{g})$ at the same temperature is :
