First virial coefficient
WebThe virial coefficients are unknown for many complex gas mixtures encountered in nature, and a cubic equation of state is useful in these cases. We first consider the van der Waals equation. The fugacity coefficient for a van der Waals gas (e.g., Lewis and Randall, 1923) is WebThe virial coefficients B, C, D, etc., are temperature dependent, and are generally presented as Taylor series in terms of 1/T. What is meant by virial equation? An equation of state of gases that has additional terms beyond that for an ideal gas, which account for the interactions between the molecules.
