Given that the equilibrium constant for the reaction
$$2 \mathrm{SO}_{2(\mathrm{~g})}+\mathrm{O}_{2(\mathrm{~g})} \rightleftharpoons 2 \mathrm{SO}_{3(\mathrm{~g})}
$$
has a value of $\displaystyle 278$ at a particular temperature. What is the value of the equilibrium constant for the following reaction at the same temperature ?
$$\mathrm{SO}_{3(\mathrm{~g})} \rightleftharpoons \mathrm{SO}_{2(\mathrm{~g})}+1 / 2 \mathrm{O}_{2(\mathrm{~g})}
$$
