There are two forms of solid sulfur: rhombic and monoclinic. The stable form of sulfur at 25°C is the rhombic form. Upon heating, the rhombic form converts to the monoclinic form, which is the stable form of sulfur at high temperatures. Consider the process:

Predict the signs of ΔH and ΔS for this process. Which form of sulfur has the more ordered structure (has the smaller positional probability)?
