3], predictions of external catalytic surface temperatures between 393-400 K are not affected by ideal Dufour conduction, but the neglect of Soret diffusion results in a 35-50 K overestimate of measured temperatures on the catalytic surface because positive thermal diffusion coefficients for oxygen impede the net diffusional mass flux of this heavy reactant toward the exothermic reaction site (Zhu et al.
