Abstract
An efficient numerical algorithm for calculating second virial coefficients of gases is outlined. When implemented in a custom computer application or a spreadsheet program, the algorithm can be used to determine the parameters of a model intermolecular potential. Using this method, students can determine the molecular-level properties of a gas based on macroscopic data related to non-ideal behavior.

Trent S. Sommers and Tal M. NahirJournal of Chemical Education2005 82 (7), 1089The temperature dependence of gas viscosities deviates significantly from the rigid-sphere model prediction of T1/2. A better relationship of Tx, where x > 1/2, is described on the basis of two theoretical approaches. A simple measurement, which could be ...
