A fluid is placed in an apparatus for measuring vapor pressure over a liquid. The results of 2 pressure-temperature measurements are given; P = 238.09 mmHg at 375.15 K P = 12.08 mmHg at 298.15 K. If these points fall on the straight-line plot of In P vs . Calculate the heat of vaporization of the substance.
