Naphthalene (C10H8) is a solid at room temperature and 100 kPa. At 100 kPa it melts at 80.2 oC. The melting point increases by 2.32 oC when the pressure is increased to 104kPa. Naphthalene boils at 219 oC, at atmospheric pressure. The vapour pressure of naphthalene at 201 oC is 67.0 kPa. The triple point of naphthalene is at 80°C and 2.1 kPa. Use this data to construct a ln(p)-T phase diagram for naphthalene and label all the regions of your diagram (you do not need to draw the diagram to scale). Please draw this diagram.

Question

Naphthalene (C10H8) is a solid at room temperature and 100 kPa. At 100 kPa it 
melts at 80.2 oC. The melting point increases by 2.32 oC when the pressure is 
increased to 104
kPa. Naphthalene boils at 219 oC, at atmospheric pressure. 
The vapour pressure of naphthalene at 201 oC is 67.0 kPa. The triple point of 
naphthalene is at 80°C and 2.1 kPa. Use this data to construct a ln(p)-T phase diagram for naphthalene and label all 
the regions of your diagram (you do not need to draw the diagram to scale). Please draw this diagram.
