Question
- Freon-12 (CCl2F2) is banned as a refrigerant because it is harmful to the ozone.
- Sketch the phase diagram of CCl2F2 using the physical constants below
Normal boiling point = -29.8 °C
Normal melting point = -158 °C
Critical temperature = 112 °C
Critical pressure = 40.8 atm
Triple point (2.42 ×10-6 atm, -157 °C)
- Calculate the heat required to bring 10.0 g CCl2F2 from -29.8 °C as a liquid to the gas phase at 10.0 °C. (molar mass = 120.91 g/mol)
Cs (gas) = 0.074 kJ/mol·K
ΔHvap = 20.1 kJ/mol
ΔHfus = 4.14 kJ/mol
