Question

state trouton's rule.

Answer 1

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. It is named after Frederick Thomas Trouton.

Trouton’s rule can be explained by using Boltzmann's definition of entropy to the relative change in free volume

Answer 2

Hey friend here is your answer

Trouton's rule states that the entropy of vaporisation 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 vaporisation is defined as the ratio between the enthalpy of a vaporisation and the boiling temperature.
