“…In this work, three different reaction locations are possible: the organic phase, the aqueous phase, or the interphase. , If the reaction takes place in a bulk phase then the mole fractions of each reactant, which are available in this phase, are used in eq . In the case of a reaction at the interphase, the mole fractions of the reactants in different phases have to be used. − This kind of reaction can occur only in two-phase systems. For this reason, it is important to know the reaction location.…”
