Phase change entropy (specifically vaporization entropy) is closely related to and can be derived from the vaporization enthalpy and the boiling point, as established by thermodynamic relationships like Trouton's rule and its extensions.
The claim states that phase change entropy can be calculated using vaporization enthalpy and boiling point. From thermodynamics, the entropy of vaporization at the boiling point is approximately equal to the enthalpy of vaporization divided by the boiling point (Delta S = Delta H / T_b), a principle underlying rules like Trouton's and Hildebrand's. Retrieved papers [7] and [9] explicitly analyze and utilize data connecting vaporization enthalpy, boiling temperature, and vaporization entropy.
