entropy of vaporization

The entropy of vaporization is the increase in entropy upon vaporization of a liquid. This is always positive since the degree of disorder increases in the transition from a liquid in a relatively small volume to a vapor or gas occupying a much larger space. At standard pressure Po = 1 bar, the value is denoted as Δ''S''ovap and normally expressed in J mol−1 K−1.
In a phase transition such as vaporization, both phases coexist in equilibrium, so the difference in Gibbs free energy is equal to zero.
: \Delta G_ = \Delta H_ - T_ \times \Delta S_ = 0,
where \Delta H_ is the heat or enthalpy of vaporization. Since this is a thermodynamic equation, the symbol T refers to the absolute thermodynamic temperature, measured in Kelvin (K). The entropy of vaporization is then equal to the heat of vaporization divided by the boiling point.
: \Delta S_ = \frac }
According to Trouton's rule, the entropy of vaporization (at standard pressure) of most liquids is about 85 to 88 J mol−1 K−1.
