Özet

In this study, a new approach to calculate the second virial coefficient of the Exp-6 potential is proposed. Over a wide temperature range, the calculated results of the second virial coefficient determined from Exp-6 potential are comparable with the calculations of second virial coefficient over Lennard-Jones (12-6) potential. As an example of application, the formulas obtained for second virial coefficient are calculated for molecules Kr,Xe,N2,Hg,CH4 and C2H6. The obtained results are in good agreement with the data available in the literature.
