Molar enthalpy of vaporization (The Clausius-Clapeyron equation)

Formula

Molar enthalpy of vaporization (The Clausius-Clapeyron equation) formula
DeltaHvap
the molar enthalpy of vaporization
T1
temperautre at one point
P1
corresponding vapor pressure at temperature T1
T2
temperature at another point
P2
corresponding vapor pressure at temperature T2

Formula description

The Clausius-Clapeyron equation for the liquid-vapor boundary may be used in either of two equivalent forms. If the corresponding temperature and pressure is known at two points, the enthalpy of vaporization can be determined.
