摘要：

A method is presented for treating kinetic data for systems in which first-order and second-order reactions proceed in parallel. Both the first- and second-order rate constants and absorbance at time f = 0 are calculated from absorbance vs. time data. The method Is, except for one minimization, a one-pass process and is easily used on a microcomputer or programmable hand-held calculator. The method will reject data not adhering to such a rate law even in the presence of reasonable noise levels. Suggestions for optimizing data collection are also presented. Using the method presented, the oxidation of formic acid by ferrate(VI) ion was investigated. © 1979, American Chemical Society. All rights reserved.
