Author(s):   McClean, R.E.; Norris, L.
Title:   A kinetic study of the reactions of vanadium, iron, and cobalt with sulfur dioxide
Journal:   Phys. Chem. Chem. Phys.
Volume:   7
Page(s):   2489 - 2497
Year:   2005
Reference type:   Journal article
Squib:   2005MCC/NOR2489-2497

Reaction:   V + SO2VO + SO
Reaction order:   2
Temperature:   296 - 571 K
Pressure:  1.33E-2 - 0.11 bar
Rate expression:   2.33x10-10 [±5.7x10-11 cm3/molecule s] e-4770 [±795 J/mole]/RT
Category:  Experiment
Data type:   Absolute value measured directly
Pressure dependence:   None reported
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Laser induced fluorescence
Comments:   V atoms were produced by the photodissociation of VCl4 at 248 nm. Rate constants were determined by following LIF decay rates of the atom in the presence of the substrate.

No pressure dependence was observed over the studied range. Uncertainties are 2 standard deviations (2 sigma).
