Express the equilibrium constant for the following reaction. \[ \mathrm{P}_{4} \mathrm{O}_{10}(\mathrm{~s}) \rightleftharpoons \mathrm{P}_{4}(\mathrm{~s})+5 \mathrm{O}_{2}(\mathrm{~g}) \] \[ K=\frac{\left[\mathrm{P}_{4}\right]\left[\mathrm{O}_{2}\right]^{5}}{\left[\mathrm{P}_{4} \mathrm{O}_{10}\right]} \] \[ K=\frac{\left[\mathrm{P}_{4} \mathrm{O}_{10}\right]}{\left[\mathrm{P}_{4}\right]\left[\mathrm{O}_{2}\right]^{5}} \] \[ K=\left[\mathrm{O}_{2}\right]^{-5} \] \[ K=\left[\mathrm{O}_{2}\right]^{5} \]
