First virial coefficient
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. WebThe first virial coefficient is (4.6) For dilute macromolecule solutions, Eq. (4.5) can be simplified as (4.7) or (4.8) This form suggests that the plot of versus c should be a straight line, and from the intercept and slop of which, we can obtain the molecular weight and the second 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
WebOther articles where virial coefficient is discussed: gas: Equation of state: virial coefficients and depend only on the temperature and the particular gas. The virtue of this equation is that there is a rigorous connection between the virial coefficients and intermolecular forces, and experimental values of B(T) were an early source (and still a … WebApr 2, 2007 · First-Principles Calculation of the Air-Water Second Virial Coefficient Published April 2, 2007 Author (s) Allan H.
