(a) 1188                      (b) 9967                     (c) 24300                    (d) 1283

1B) A liquid with an enthalpy of vaporization, DHv, of 32.80 KJ/mole has a normal boiling point at 39.20°C. Its vapor pressure at 57.35°C is:

(a) 1728 Torr              (b) 2644 Torr             (c) 2185 Torr             (d) 1521 Torr
