Given that the equilibrium constant for the reaction, 2SO2(g) + O2(g) $\rightleftharpoons$ 2SO3(g) has a value of 278 at a particular temperature. What is the value of the equilibrium constant for the following reaction at the same temperature ? SO3(g) $\rightleftharpoons$ SO2(g) + ${1 \over 2}$ O2(g)

Question

Given that the equilibrium constant for the reaction,
2SO_2(g) + O_2(g) $\rightleftharpoons$ 2SO_3(g)
has a value of 278 at a particular temperature. What is the value of the equilibrium constant for the following reaction at the same temperature ?
SO_3(g) $\rightleftharpoons$ SO_2(g) + ${1 \over 2}$ O_2(g)
