摘要：

Nitrogen and nitrous oxide are the only oxidation products produced when excess hydrazoic acid is oxidized by bromate ion in perchloric acid-lithium perchlorate solution. The reduction products of the bromate ion are hypobromous acid and bromine. The rate expression is -d[BrO3-]/dt = K0[BrO3-] [HN3] [H+]. At 25.0° and 2.0 M ionic strength, the value of k0 is (6.22 ± 0.06) × 10-2 M-2 sec-1, and the associated activation parameters are ΔS‡ = 13.5 ± 0.2 kcal/mol and ΔS‡ = -18.7 ± eu. Oxygen-18 tracer studies reveal that most, but not all, of the oxygen in the nitrous oxide product is derived from the solvent. © 1969, American Chemical Society. All rights reserved.
