Conclusions
-
1.
The reaction of hydrogen with oxygen (H2∶O2∶Ar=2 ∶1∶60) in shock waves at the temperature 1190–1390°K and pressures 1–3.5 atm is accompanied at the early stages of the reaction by a substantial superequilibrium vibrational excitation of OH radicals and water molecules and electronic excitation of OH radicals and sodium atoms.
-
2.
During the induction period the electronic excitation of OH is due chiefly to the reaction H+H2+O2→OH*+H2O, while at higher pressures it is also determined by the recombination of O and H. The following reactions are the most probable for an explanation of the vibrational excitation of water molecules: HO2+H2→ H2O *+OH and OH+H2→H2O*+H.
-
3.
Superequilibrium electronic excitation of Na atoms apparently occurs in collisions with OH and H2O possessing a sufficient reserve of vibrational energy.
