At the transition temperature of 95.4°C, the enthalpy of transition from rhombic to monoclinic sulfur is 0.38 kJ mol-1.
a. Calculate the entropy of transition under these conditions.
b. At its melting point, 119°C, the enthalpy of fusion of monoclinic sulfur is 1.23 kJ mol-1. Calculate the entropy of fusion.
c. The values given in parts (a) and (b) are for 1 mol of sulfur; however, in crystalline and liquid sulfur, the molecule is present as S8. Convert the values of the enthalpy and entropy of fusion in parts (a) and (b) to those appropriate for S8.
