Abstract
The rate of decrease of higher order corrections to various transport coefficients of binary gas mixtures has been established for a temperature range (200K<or=T<or=2000K) in the case of the LJ (12-7) potential. The authors study shows that, depending upon the experimental accuracy, at least second- order calculations for viscosity and third-order calculations for other coefficients of binary mixtures should be performed to check the validity of an intermolecular potential. In obtaining these results, general expressions for transport coefficients have been written in terms of the inverse of matrices. The utility of these expressions for computer programming has been indicated.
