)methanol, ch3oh, has an entropy change of vaporisation of 104.1 jk-1 mol while methanoic acid, hcooh, has an entropy change of vaporisation of 61.8 j k- mol-1. explain why these values differ from those predicted by trouton's rule. (6 marks) (c) the enthalpies of combustion for methanol (chsoh), ethanoic acid (ch; cooh) and carbon monoxide (co) are given below ch3oh +3202 co2 + 2h20 ch3cooh202 2co2 + 2h20 co + 1/2o2 → co2 δη =-726 kjmol-1 ah -875 kjmol-1 ah--283 kjmol-1 caculate the enthalpy ort oloing reaceion: ch3oh +co ch3cooh
