Question 1

At 25°C, ΔH° = 1.895 kJ and ΔS° = -3.363 J/K for the transition

C(graphite) → C(diamond)

Based on these data,
◦ diamond is more stable than graphite below 290°C and graphite is more stable than diamond above 290°C.
◦ diamond is more stable than graphite at all temperatures at 1 atm.
◦ graphite is more stable than diamond below 290°C and diamond is more stable than graphite above 290°C.
◦ graphite cannot be converted to diamond at 1 atm pressure.

Question 2

For bromine, ΔH°vap = 30.91 kJ/mol and ΔS°vap = 93.23 JK-1mol-1 at 25°C. What is the normal boiling point for bromine?
◦ 58°C
◦ 25°C
◦ 332°C
◦ 124°C
