Chapter 18, Problem 77GQ
Sulfur undergoes a phase transition between 80 and 100 °C.
S8(rhombic) → S8(monoclinic)
ΔrH° = 3.213 kl/mol-rxn ΔrS° = 8.7 J/K · mol-rxn
- (a) Estimate ΔrG° for the transition at 80.0 °C and 110.0 °C. What do these results tell you about the stability of the two forms of sulfur at each of these temperatures?
- (b) Calculate the temperature at which ΔrG° = 0. What is the significance of this temperature?

When two solutions, one of 0.1 M KCl (I) and the other of 0.1 M MCl (II), are brought into contact by a membrane. The cation M cannot cross the membrane. At equilibrium, x moles of K+ will have passed from solution (I) to (II). To maintain the neutrality of the two solutions, x moles of Cl- will also have to pass from I to II. Explain this equality: (0.1 - x)/x = (0.1 + x)/(0.1 - x)
