Homework Answers
Rhombic form of sulfur is more stable than monoclinic forms at temperature below 95 DegC thus system would like to be in rhombic state at these temeprature levels.
So entropy change will be negative from rhombic to monoclinic form (because entropy increase only if the resultant form is more stable).
I hope it clarifies. if you have the Delta H and temeprature data then you can calulathe actual amount of entrop changed.

Entropy and Solid Phase Change It is quite common for a solid to change from one solid state structure to another at a temperature below its melting point. For example, sulfur undergoes a phase change from the a-orthorhombic form (Sg; density=2.07 g/cm3) to the B-monoclinic form (Sg; density=2.00 g/cm3) as it is warmed above 95.3 °C. Assuming that AH for this phase change is 0.310 kJ/mol, calculate AS for this phase change. Submit Answer Tries 0/5
