碩士 === 國立交通大學 === 應用化學系 === 88 === The kinetics of the reaction of Cl with SO2 have been studied using laser photolysis - resonance fluorescence technique between 232 - 298 K and at pressure 51 - 505 Torr.
Cl + SO2 + M → ClSO2 + M
Cl radicals were produced by photolyzing Cl2 molecules with a Nd - YAG laser output at 355nm. We obtain the low-pressure limited and high-pressure limited rate constant at T = 298 K as
k0(298)=(1.58 ± 0.26)× 10-33 cm6molecule-2s-1,
k∞(298)=(8.70 ± 0.37)× 10-15 cm3molecule-1s-1 。
We also observed equilibrium at this temperature and proposed the formation of adduct ClSO2. The equilibrium constant was obtained from fitting the data using a software FACSIMILE.
Kc(298)=(1.1 ± 0.2)× 10-16
At T < 298 K, no equilibrium was observed and the Cl decay rate increased with reaction time. The rate constant determined from FACSIMILE fitting which was attributed to secondary reaction between Cl and adduct.
