Question: Ethanol, with H v a p = 4 0 . 5 k J m o l - 1 , has a higher H v a

Ethanol, with Hvap=40.5kJmol-1, has a higher Hvap than methanol, which is 35.2kJmol-1, due to its larger size and greater intermolecular forces. Because the Hvap for ethanol is larger, we would expect that for the two liquids to reach the same vapor pressure, the temperature for ethanol would have to be higher. If the vapor pressure is 0.0992atm at 27.3C, what would the temperature be when the vapor pressure is 2.22 atm?
The temperature will be
