Thermodynamic-Level Description of Chemical, Electrochemical, and Ion Transport Mechanisms

Abstract

One of the few chemical systems for which concentration fluctuations have been measured is the association-disassociation reaction of beryllium and sulfate ions in aqueous solution. Earlier, using conventional fast-reaction techniques, the mechanism of association was deduced to consist of the two elementary reactions

$$ {\text{Be}}_{{\text{aq}}}^{2 + } + {\text{SO}}_{4{\text{aq}}}^{2 - } \rightleftarrows {\text{Be}}_{{\text{aq}}}^{2 + } {\text{SO}}_{4{\text{aq}}}^{2 - } $$
