At $800 \mathrm{~K}$ in a closed vessel, the molar concentrations of $\mathrm{N}_2, \mathrm{O}_2$ and $\mathrm{NO}$ at equilibrium are
$3.2 \times 10^{-3} \mathrm{M}, 4.2 \times 10^{-3} \mathrm{M}$ and $2.8 \times 10^{-3} \mathrm{M}$ respectively. The approximate values of $\mathrm{K}_{\mathrm{c}}$ and $\frac{1}{\mathrm{~K}_{\mathrm{c}}}$ for the following reaction are respectively
$\mathrm{N}_{2(\mathrm{~g})}+\mathrm{O}_{2(\mathrm{~g})} \rightleftharpoons 2 \mathrm{NO}_{(\mathrm{g})}$
