Résumé

The focus here is to obtain the Compressibility Factor (CF) for pure fluids from a Configurational Integral (CI). In this direction, we came up with a formula from the (CI) which consistently gives the compressibility factor for a given intermolecular potential. From this formula we obtain the Compressibility Factor (CF) for a number of existing intermolecular potentials. The results here are compared with the Carnahan Sterling Equation of state (EOS) since it is one of the accepted EOS. There is a strong positive correlation between the results.
