Title:   Measurement of the Rate Constants for the Reactions of the IO Radical with Sulfur-Containing Compounds H2S, (CH3)2S, and SO2
Journal:   Kinet. Catal.
Volume:   41
Page(s):   485 - 491
Year:   2000
Reference type:   Journal article
Squib:   2000LAR/MES485-491

Reaction:   SO2 + IO → Products + I
Reaction order:   2
Temperature:   343 K
Pressure:  3.33E-3 bar
Rate expression:   5.6x10-15 [cm3/molecule s]
Rate constant is an upper limit.
Bath gas:   He
Category:  Experiment
Data type:   Derived from fitting to a complex mechanism
Pressure dependence:   None reported
Experimental procedure:   Flow tube - Data taken vs distance
Excitation technique:   Direct photolysis
Time resolution:   In real time
Analytical technique:   Resonance fluorescence
Comments:   The upper limit of the homogenous rate coefficient is an estimate derived from a data plot that found the sum of homogeneous and heterogeneous reaction rate coefficients, khomo + khet = (2.1 +/- 0.7) x 10-14 cm3 molecule-1 s-1.
