Consideration of Terms Proportionate to (1/v)2c in the Distribution Function Expansion and their Contribution to the Thermodynamic Properties of Strong Electrolytes Solutions

It is common knowledge that when deriving the distribution function equation one must use the expansion of distribution function as the inverse of the per one particle volume series (1/v = N/v). When doing such expansion, one usually restricts himself by the first power of 1/v, or, at best, the second power of 1/v. The question naturally arises: how much is the value of omitted terms and what is their contribution to the properties of a particular thermodynamic system? Specific calculations have not been reported but, as a rule, it is affirmed that their role is negligible. © 2001 IOS Press.
