Use of rotating single probe in studies of ionization of additives to premixed flames. Part 3.—Dissociative recombination of hydronium ions with electrons

Abstract

The dissociative recombination H₃O⁺+ e^–→neutral products, has been studied in H₂+ O₂+ N₂+ C₂H₂ flames by means of a probe calibrated through a confirmed procedure based upon alkali metal ionization. Its rate coefficient was determined in the temperature range 2020-2520 K to be 0.076 ± 0.020 × T^{–1.6 ± 0.3} ml molecule^–1 s^–1.
