6.4. The vapor pressure of ethylene glycol at several temperatures is given below:

T (C) 79.7 105.8 120.0 141.8 178.5 197.3

p* (mmHg) 5.0 20.0 40.0 100.0 400.0 760.0

Use a semilog plot based on the Clausius-Clapeyron equation to derive an equation for p* (mm Hg) as a function of T (C). From the plot, estimate the heat of vaporization of ethylene glycol in kJ/mol.

Clausius-Clapeyron equation: ln p* = -Hv/RT + B
