Question:

Trouton's rule states that for many liquids at their normal boiling points, the standard molar entropy of vaporization is about 88 J/mol-K.
(a) Estimate the normal boiling point of bromine, Br2, by determining ΔH°vap for Br2 using data from Appendix C. Assume that ΔH°vap remains constant with temperature and that Trouton's rule holds.
(b) Look up the normal boiling point of Br2 in a chemistry handbook or at the WebElements Web site (www.webelements.com).
