摘要
The rate constant for the gas-phase reaction of O_3 and Lewisite was studied in air using the smog chamber technique. The experiments were carried out under pseudo-first-order reaction conditions with [O_3] [Lewisite]. The observed rate constant of O_3 with Lewisite was（7.83 ± 0.38） × 10^（-19）cm^3/（molecule·sec） at 298 ± 2 K. Lewisite was discussed in terms of reactivity with O_3 and its relationship with the ionization potential. Our results show that the rate constant for the gas-phase reaction of O_3 with Lewisite is in line with the trend of the rate constants of O_3 with haloalkenes.
