The Clausius-Clapeyron equation can be used to estimate how the boiling point changes with pressure, or how the vapor pressure changes with temperature.

In this example problem, we solve for vapor pressure using the Clausius-Clapeyron equation. Determine the vapor pressure in mm Hg of a substance at 45 degrees Celsius if its normal boiling point is 115 degrees Celsius and its enthalpy of vaporization is 57.9 kJ/mol.
