Abstract
The validity of Onsager's reciprocal relations in ternary diffusion was verified by transformation of the thermodynamic expressions into concentration gradient form while assuming no volume flow. A table containing several systems is presented, and the estimated error is assigned solely to uncertainties in diffusion coefficients based on concentration gradients; however, some error undoubtedly exists in the activity coefficients since they were estimated in the absence of experimental data.
