$$2 \mathrm{NOCl}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}(\mathrm{~g})+\mathrm{Cl}_2(\mathrm{~g})
$$
In an experiment, $\displaystyle 2.0$ moles of NOCl was placed in a one-litre flask and the concentration of NO after equilibrium established, was found to be $\displaystyle 0.4 \mathrm{~mol} / \mathrm{L}$. The equilibrium constant at $\displaystyle 30^{\circ} \mathrm{C}$ is \_\_\_\_ $\displaystyle \times 10^{-4}$.
