Cálculo del segundo y tercer coeficiente del virial con el potencial de Lennard-Jones, parte II

Abstract

This article is the second part of the work presented by Reyes and Galo, we estimate the third virial coefficient using the classic approach because the Argon, the gas selected, has a length thermal wave smaller than the diameter of collision and the quantum effect is negligible. The potential used to calculate the third virial coefficient is the Lennard-Jones potential, the results were compared with experimental coefficients reported in the scientific literature, theoretical results differ from the experimental results indicating that our model is not suitable for describe the interaction of clusters with three particles. Equations for the third virial coefficient is calculated using minimum square, because by these equations can be calculated thermodynamic properties of interest.
