| Résumé : | A statistical theory of associated solutions is developed, taking into account the two main effects of association, (a) evolution of heat, (b) decrease in the number of possible orientations of the associated molecules. The theory is first applied to the association of a solute molecule with the solvent, and then to alcohols. It predicts the experimental behaviour of " unhindered" alcohols, for which the association constant of monomers into dimers is lower than that of higher order complexes. The excess free energy and excess enthalpy, deduced from this model and from spectroscopic data, for the system, CH3OH + CCl4, are in agreement with Scatchard's experimental values, without introducing any arbitrary parameter. |
