Question
Construct liquid-vapour and solid-vapour phase boundaries for iodine l2 given the
following:
> Enthalpy of vaporization = 41.57 kJ/mol
> Enthalpy of fusion = 14.73 kJ/mol
Normal boiling point = 386.8 K
> The sublimation pressure is 52.5 Torr at 113.6 °C
Make a table of P (atm) and T (K) using reasonable range of temperatures. The
table must include the given normal and triple points. Show one example of your
calculations for both phase boundaries (total of 2 examples only).
Make a plot of p (atm) versus T (K) for all the points in the table, and write all
labels on the plot.
Estimate the triple point temperature and pressure.
Comment on slope of the two boundaries.
