Based on the film theory and by means of linearization of the principal differential balance equation an approximate expression has been derived for the enhancement of transfer of species A from the interface by the following reaction with the components B and C: A + mB → nC + pP and A + C ⇄ D. The former of these reactions is irreversible while the second is an equilibrium one. The asymptotic behaviour of the derived relationships has been verified and an error has been estimated of the prediction of the enhancement factor due to the linearization.
