Figure 3
A comparison of O2 loss reaction rates per one O2 molecule (= reaction rate / O2 number density) under the 6% H2 (solid line) and 0.01% H2 (dashed line) conditions. The black and blue lines show the reaction rates of \({\text{H}} + {\text{O}}_{2} + {\text{M}} \to {\text{HO}}_{2} + {\text{M}}\) (R4) and \({\text{HCO}} + {\text{O}}_{2} \to {\text{HO}}_{2} + {\text{CO}}\) (R3), respectively.
