✦ Synopsis

Steady, multicomponent diffusion through two phases, accompanied by an arbitrary number of reversible reactions between the diffusing species, is formulated as a boundary value problem. The results, achieved after linearization, indicate that non-equilibrium reaction in the neighborhood of the interface is possible even though equilibrium may exist in the bulk phases. The effect of the reaction(s) is to augment the transfer as in the case of single films. The extent of this augmentation effect for a pair of simultaneous, coupled reactions of the form A G= 2B B=C+D is shown. A reaction coupling effect increases the transfer above that due to each reaction occurring alone.
