Kinetics of dissociative recombination of free electrons with hydronium ions in premixed flames

Allan N. Hayhurst  and  N. Roland Telford 

Abstract

The rate coefficient for the gas phase recombination of H3O+ ions and free electrons in H3O++ e–→ neutral products has been measured in atomospheric pressure flames of H2+ O2+ N2 over the temperature range 2025–2445 K. Concentrations of ions were arrived at by sampling each flame into a mass spectrometer. The recombination coefficient was not found to vary significantly with temperature, being 4.1 ± 1.0 × 10–7 ion–1 cm3 s–1 over this temperature range. This corresponds to a cross-section (πσ2) for the process of about 1.5 × 10–18 m2.
