This work is an experimental test of the Stefan‐Maxwell equations as applied to cocurrent, steady state gaseous diffusion of two species through a stagnant third component. The Stefan capillary tube method was used to measure the diffusion rates. The use of constant evaporating binary liquid mixtures made possible boundary conditions that were invariant with time. Total molar losses were compared with the predictions of the theory to demonstrate the validity of the equations under conditions of a significant convective flux.
