According to the Clausius-Clapeyron equation, the slope of the line relating the natural logarithm of vapor pressure and the reciprocal of temperature is $- \frac { \Delta _ { \text {vap } } H } { R }$, where $\Delta _ { \text {vap } } H$ is the enthalpy of vaporization and $R$ is the universal gas constant.
