Maxwell — Boltzmann statistics, with corrections for the quantum character of energy changes and the indistinguishable nature of molecules, works perfectly well when we consider systems of non-interacting molecules. If particles are interacting with each other, then the description of such systems by Maxwell — Boltzmann statistics becomes extremely difficult if not impossible. For example, consider a system of positive and negative ions interacting in pairs. The potential energy of such a system is: 2.1$$ U = \sum\limits_i {\sum\limits_j {\frac{{e_i e_j }} {{2r_{ij} }}} } $$
