Trouton's rule
Trouton's rule[′trau̇t·ənz ‚rül] (physical chemistry) An approximation rule for the derivation of molar heats of vaporization of normal liquids at their boiling points. (thermodynamics) The rule that, for a nonassociated liquid, the latent heat of vaporization in calories is equal to approximately 22 times the normal boiling point on the Kelvin scale. |
