Absolute rate of the reaction of hydrogen atoms with ozone from 219–360 K

Absolute rate constants for the reaction of atomic hydrogen with ozone were obtained over the temperature range 219–360 K by the flash photolysis–resonance fluorescence (FP–RF) technique. The results can be expressed in Arrhenius form by k = (1.33±0.32) ×10−10 exp(−449±58/T) cm3 molecule−1 s−1 (two standard deviations). The present work is compared to two previous determinations and is theoretically discussed.
