(a) The normal boiling point of benzene is 353.1 K. Estimate the boiling point of benzene in a vacuum still at 2.6 kPa pressure. Use Trouton's rule.
(b) The vapor pressure of solid benzene is 0.3 kPa at 243 K and 3.2 kPa at 273 K. The vapor pressure of liquid benzene is 6.2 kPa at 283 K and 15.8 kPa at 303 K. Estimate the heat of fusion of benzene.
