chemical equilibrium, non-ideal systems, solid sphere model, indifferent solvent.
Statistics-thermodynamic analysis of dimerization equilibrium in the frames of the solid sphere model in indifferent solvent with its own value of diameter was carried out. The positive and negative deviations from the ideality in the dimerized solid-sphere system in the presence of the indifferent solvent can be described rather simply with the minimal set of parameters, characterizing the ratio of particles sizes of the mixture components.
