Bag et al. [12], measured the conductance of Co (III) complex monochloride in MeOH-H2O mixtures at different temperatures (25, 30, 35, 40 °C). It was found that, at a particular temperature ΔG0 becomes more negative. This indicates that ion-pair association is favored with lowering of dielectric constant of medium. A positive entropy change is explained on the assumption that iceberg structure around the cation is broken when association takes place leading to an increase in the degree of disorderness [13].
