Solid sulfur undergoes a phase transition between monoclinic (m) and orthorhombic (o) phases at a temperature of 368.3 K and pressure of 1 bar. Calculate the difference in gibbs energy between monoclinic sulfur and orthorhombic sulfur at 298 K and a pressure of 1 bar. take the enthalpy in each phase to be given by the following expressions.

Monoclinic phase: entropy = sm = 13.8 + 0.066T (J/mol K)

Orthorhombic phase: entropy = so = 11.0 + 0.071T (J/mol K)
