In the analysis of combustion problems and other multicomponent reacting systems, it is important to account for the relevant transport properties of the reacting mixture. This Demonstration is concerned with computing the ordinary diffusion coefficients of a mixture. The thermal diffusion coefficients, which describe the Soret effect, are not considered.
