Q. At the temperature T(K) for the reaction $\ce{X_2O_{4(i)} -> 2XO_{2(g)} \, \Delta \,U\, = \,x\, kJ \, mol^{-}, \Delta S = y \, JK^{-1} \, mol^{-1} }$. Gibbs energy change for the reaction is
(Assume $\ce{X2O4. XO2}$ are ideal gases) $\Delta \,U = x\, kJ\, mol ^{-1}, \Delta S = y\, JK ^{-1} mol ^{-1}$
