2. The compound $$\mathrm{NOCl}$$ decomposes to nitric oxide and chlorine according to the following equation: $$2\mathrm{NOCl}(\mathrm{g})?2\mathrm{NO}(\mathrm{g})+{\mathrm{Cl}}_2(\mathrm{g})$$ Suppose that $$0.180\mathrm{mol}\mathrm{NOCl}$$ is placed in a 2.00-L flask at a given temperature. When equilibrium has been established, it is found that the concentration of $$\mathrm{NO}$$ is $$0.0572\mathrm{M}$$. Calculate the equilibrium constant for this reaction.
