What is the enthalpy of vaporization for a compound that has a vapor pressure of #"135 torr"# at #52^@ "C"# and #"24.3 torr"# at #0^@ "C"#?
Your compound's enthalpy of vaporization will be close to 24.3 kJ/mol.
To determine the enthalpy of vaporization,
So, plug in your values into the above equation and solve for
Rounded to three sig figs and expressed in kJ, the answer will be
Note that this is only an estimate, under the assumption that in the pressure and temperature range examined, the enthalpy of vaporization is essentially linear, but that is not always the case.
