Ra. Guiradolopez et F. Aguileragranja, STUDY OF A DIATOMIC SOLUTION USING THE CL USTER-VARIATION METHOD, Revista Mexicana de Fisica, 41(4), 1995, pp. 493-506
The thermodynamic behaviour of a binary solution of diatomic molecules
is studied using the pair approximation of the cluster-variation meth
od. Analytical expressions for the osmotic pressure, the chemical pote
ntial and the grand potential are obtained. In addition, the phase dia
gram is calculated. The results are compared with Flory's theory.
