Construct solid-liquid and solid-vapour phase boundaries for carbon tetrachloride CCl 2 given

 

Construct solid-liquid and solid-vapour phase boundaries for carbon tetrachloride CCl 2 given the following: Density of solid CCl2 = 1.809 g/cm Density of liquid CCl2 = 1.59 g/cm Enthalpy of fusion = 3.28 kJ/mol Normal melting point = 250 K Enthalpy of vaporization = 29.82 kJ/mol The sublimation pressure is 270 Pa at 232 K a) 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). b) Make a plot of p (atm) versus T (K) for all the points in the table, and write all labels on the plot. c) Estimate the triple point temperature and pressure. d) Comment on slope of the two boundaries.
