The quantity of the partial derivative of second virial coefficients with respect to temperature in reduced form, T * ∂B * /∂T * has been computed for an exp‐6 intermolecular potential\documentclass{article}\pagestyle{empty}\begin{document}$$ \varphi ({\rm r}) = \varepsilon \left\{{\frac{6}{{\alpha - 6}}\exp \left[{\alpha \left({1 - \frac{{\rm r}}{{{\rm r}_{\rm m}}}} \right)} \right] - \frac{\alpha }{{\alpha - 6}}\left({\frac{{{\rm r}_{\rm m} }}{{\rm r}}} \right)^6 } \right\} $$\end{document}The results are tabulated over the reduced temperature range T * from 0.4 to 400, and for seven values of the parameters α from 12 to 15. The outputs lead us to lay the foundation for the applications of the theoretical virial type equation of state (6) like VLW using the best form exp‐6 for high pressure studies.
