At atmospheric pressure, the boiling point of bromine is 59.2 °c. use trouton's rule to estimate the enthalpy of vaporisation of bromine. (4 marks) -1 methanol, chsoh, has an entropy change of vaporisation of 104.1 j k mol while methanoic acid, hcooh, has an entropy change of vaporisation of 61.8 j k-1 mol-1. explain why these values differ from those predicted by trouton's rule. (6 marks) the enthalpies of combustion for methanol (chsoh), ethanoic acid (ch3cooh) and carbon monoxide (co) are given below: ch3oh + 3/202-> co2+ 2h2o ch3cooh + 202-> 2co2 +2h2o co + 1/202-co2 ah726 kjmol-1 ah-875 kjmol-1 ah- -283 kjmol-1 calculate the enthalpy change for the following reaction: ch3oh + co → ch3cooh
