Abstract
It is shown that the closure of the model equation of Anderson and Witting by a moment method leads to transport coefficients of a relativistic gas wh ich differ from those obtained by the usual Chapman and Enskog method. The transport coefficients obtained in the two closures coincide in the non-rel ativistic limiting case but depart from each other in the relativistic and ultra-relativistic regions.
