The dependence of the rate of N/sub 2/O formation on the reactants and on pH in the oxidation of NH/sub 2/OH by Fe(III) has been investigated over a range of reactant concentrations, with emphasis on low concentrations of hydroxylamine. The production rate of N/sub 2/O was pseudo first order with respect to total iron, pseudo first order or less with respect to total hydroxylamine, and inversely proportional to (H/sup +/)/sup 2.5/. The reaction is highly sensitive to temperature. Of the competing reactions producing nitrogenous products other than N/sub 2/O, at least one is catalyzed by light. An empirical rate law, based on the total concentrations of the reactants, is presented, and a more general rate law, based on the concentrations of presumed reactive species, is derived.
