Trouton's Rule

[505095793]

Can someone further explain Trouton's rule and how it relates to vaporization?

[Hannah Yates 1K]

I believe that Troutons rule is just stating that many liquids have about the same enthalpy of vaporization. Which means that they all take about the same amount of energy to vaporize.

Trouton's rule states that the entropy of vaporization is almost the same value, about 85–88 J K−1 mol−1, for various kinds of liquids at their boiling points. The entropy of vaporization is defined as the ratio between the enthalpy of vaporization and the boiling temperature.
