WebJan 30, 2024 · Trouton's rule says that for many (but not all) liquids, the entropy of vaporization is approximately the same at ~85 J mol −1 K −1. The (partial) success of the rule is due to the fact that the entropy of a gas is considerably larger than that of any liquid. Therefore, the entropy of the initial state (e.g. the liquid) is negligible in ...
