ABSOLUTE RATE OF 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) cm 3 molecule-1s-1 (two standard deviations). The present work is compared to two previous determinations and is theoretically discussed. © 1978 American Institute of Physics.
