Question 1

Elemental sulfur exists in two crystalline forms, rhombic and monoclinic. From the following data, calculate the equilibrium temperature at which monoclinic sulfur and rhombic sulfur are in equilibrium.    
 
ΔHf° (kJ/mol)
S° (J/K·mol)
S (rhombic)
0
31.880
S (monoclinic)
0.30
32.553
 

​


◦ 446 K
◦ 202 K
◦ –202 K
◦ –446 K
◦ 0 K

Question 2

For a certain process at 355 K, ΔG = –11.8 kJ and ΔH = –9.2 kJ. Therefore, ΔS for the process is

◦ 0 J/K·mol
◦ 7.3 J/K·mol
◦ –7.3 J/K·mol
◦ –25.9 J/K·mol
◦ 25.9 J/K·mol
