The boiling point and freezing point of sulfur dioxide are -10C and -72.7C (at 1 atm), respectively.

Question:

The boiling point and freezing point of sulfur dioxide are -10°C and -72.7°C (at 1 atm), respectively. The triple point is -75.5°C and 1.65 ( 10-3 atm, and its critical point is at 157°C and 78 atm. On the basis of this information, draw a rough sketch of the phase diagram of SO2?
