Abstract

<p>The facilitated transfer of sodium ion across the water/nitrobenzene interface was examined by faradaic impedance measurements at the thermodynamic equilibrium potential. Kinetic data for the interfacial reaction Na<sup>+</sup>(w) + L(n) ↔ NaL<sup>+</sup>(n) (L = dibenzo-18-crown-6, w = water, n = nitrobenzene) were confronted with the theoretical predictions for three possible reaction mechanisms, and a conclusion was reached that the reaction occurs via a single electrochemical step. Its pseudo-first order rate constant depends on the interfacial potential difference and falls between 0.01 and 1 cm s<sup>-1</sup>, i.e. it is comparable with the first order rate constant for a simple ion transfer.
