Question: Construct solid-liquid and solid-vapour phase boundaries for iodine I 2 given the following: Density of solid I 2 = 4.93 g cm 3 Density

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.
