Title:   CO Chemiluminescence and Kinetics of the C2 + O2 Reaction
Journal:   J. Phys. Chem. A
Volume:   105
Page(s):   3182 - 3189
Year:   2001
Reference type:   Journal article
Squib:   2001FON/FER3182-3189

Reaction:   O2 + C2CO + CO
Reaction order:   2
Temperature:   298 - 711 K
Pressure:  1.30E-2 - 0.33 bar
Rate expression:   1.1x10-11 [cm3/molecule s] e-3168 [J/mole]/RT
Bath gas:   Ar
Category:  Experiment
Data type:   Absolute value measured directly
Pressure dependence:   Rate constant is pressure dependent
Experimental procedure:   Stirred flow reactor(PSR etc.)
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Vis-UV emission
Comments:   The C2 has been produced from the C2Cl4+K reaction. Also in a high temperature photochemistry reactor C2 Has been generated by 193 nm multiphoton dissociation of C2Cl4.Accuracy of the rate constant is estimated to be about +/-21%.
