Abstract
Calculations have been made of equilibrium concentrations of hydroxyl radicals and of hydrogen and oxygen atoms in moist carbon monoxide flames. Comparison with burning velocities, measured by Jahn by the Bunsen burner method, reveals a close correlation between observed burning velocities and such calculated hydrogen atom concentrations. Only a slight correlation exists with hydroxyl radical concentrations and none at all with calculated oxygen atom concentrations. A theoretical basis for these observations will be presented in a subsequent paper.
