Textbook Question
Chapter 19, Problem 19.58E

Knudsen effusion cells are used to determine vapor pressures of high-temperature materials. For example, a Knudsen cell is filled with tungsten and heated to 4500 K in a vacuum. Measurements show that the cell loses mass assumed to be W vapor at the rate of 2 .113 grams per hour out of a hole that is 1.00 mm 2 in area. Calculate the vapor pressure of W at 4500 K .

Plot lnP vs 1/T (in K!) and determine the enthalpy of vaporization of nitric acid at its boiling temperature.  The vapor pressure of nitric acid is as follows: T(C):  0  20  50  70  90  100 P(Torr):  14.4  47.9  208  467  937  1282
The vapor pressure, p, of nitric acid varies with temperature as follows: Ꝋ/oC 0 20 40 50 70 80 90 100 p/kPa 1.92 6.38 17.7 27.7 62.3 89.3 124.9 170.9   What are. The normal boiling point and The enthalpy of vaporization of nitric acid?
The vapour pressure of hexane between -10°C and +90°C fits the expression log(p/Torr) = 7.724 – 1655/(T/K). Calculate the enthalpy of vaporization.
