Vapor pressure (Given temperature,pressure, enthalpy of vaporization)

Formula

Vapor pressure (Given temperature,pressure, enthalpy of vaporization) formula
P2
vapor pressure of interest at T2
T2
the corresponding temperautre
T1
the temperature at anther point
P1
the corresponding vapor pressure at the known temperature T1
DeltaHvap
the molar enthalpy of vaporization

Formula description

The Clausius-Clapeyron equation for the liquid-vapor boundary may be used in either of two equivalent forms. This can be used to predict the temperature at a certain pressure, given the temperature at another pressure, or vice versa.
