Possible use of chronopotentiometry at the interface between two immiscible liquid phases to the studies of homogeneous chemical reactions

The theoretical potential-time dependence corresponding to the electron transfer reaction proceeding at the interface between two immiscible liquid phases with the redox pairs O1/R1 in the aqueous (aq) phase and O2/R2 in the non-aqueous (non) phase, that is complicated by the reaction R1(aq) + Z(aq) → O1(aq) in the aqueous phase, has been derived under the galvanostatic conditions. Moreover, a method for the determination of the formal rate constant kf for the given homogeneous chemical reaction is proposed.
