Abstract

In this study, the rate constant of the reaction between hydroiodic acid and a chlorine atom was measured using the resonance fluorescence (RF) method in a flow reactor within the temperature range of 298–366 K. Measurements were performed by detecting the RF of both chlorine atoms and iodine atoms, the latter being a product of this reaction. In both cases, similar expressions describing the temperature dependence of the rate constant were obtained. A possible explanation for the observed decrease in the reaction rate constant with increasing temperature in the reactor is proposed.
