Construct solid-liquid and solid-vapour phase boundaries for iodine I₂ given the following:

• Density of solid I₂ = 4.93 g cm^─3
• Density of liquid I₂ = 3.96 g cm^─3
• Enthalpy of fusion = 14.73 kJ/mol
• Normal melting point = 386.8 K
• Enthalpy of vaporization = 41.57 kJ/mol
• The sublimation pressure is 0.30844 Torr at 25.00 ^oC

Make a plot of p (atm) versus reasonable range of temperatures (K) and write all labels on the plot.

Estimate the triple point temperature and pressure.

Comment on slope of the two boundaries.
