Useful Equations - The Clapeyron Equation

Useful Equations - The Clapeyron Equation. Gives the rate of change of the vapor pressure with temperature, dp/dT, in terms of the enthalpy of vaporisation, ?H vap , volume of the liquid, V l , and volume of the vapor, V v , at temperature T and at a pressure equal to the vapor pressure.
