Antoine Vapor Pressure Equation

The Antoine equation is derived from the
ClaussiusClapeyron equation which describes the phase
transition between two phases of matter. The Antoine equation
describes the relation between saturated vapor pressure and
temperature of a pure component. For solvent blends the
Raoult's law applies.
