Equilibria and Kinetics Involving Aqueous BrCl^·–

The aqueous radical anion BrCl·– is frequently invoked in mechanisms describing the chemistry of advanced oxidation processes and other environmental situations. There are at least 58 publications with mechanisms involving this species where the rate constants assigned to the steps involving BrCl·– yield reversible loops with loop products that are in serious violation of the principle of detailed balancing. Here, we summarize these violations, identify their origins, and provide suitable corrections that do not violate the principle of detailed balancing.
