At 298 K, the entropy of rhombic sulphur is 32.04 J mol\(^{-1}\) K\(^{-1}\) and that of monoclinic sulphur is 32.68 J mol\(^{-1}\) K\(^{-1}\). The heats of combustion are respectively \(-298246\) and \(-297948\) J mol\(^{-1}\). \( \Delta G \) for the reaction: S\(_{\text{rhombic}}\) \( \rightarrow \) S\(_{\text{monoclinic}}\) will be
