The free enthalpy of complex formation, corrected for the involved change of the number of particles, is described as a sum: δ G ta + δ G tu (= δ G ‐ δ G m ), which permits the separation of the temperature dependent terms. Following Gurney, it is supposed that the temperature dependent free enthalpy δ G ta varies in the same way as the reciprocal of the dielectric constant of the solvent. This model furnishes some relations which permit a correct description of the complex formation in terms of an electrovalent and of a nonelectrovalent interaction.
