Summary
-
1.
The absolute rate constants of the reactions of oxygen atoms with methane and ethane at different temperatures were measured.
-
2.
The activation energies of the reactions of oxygen atoms with methane and ethane equal to 7800 and 5200 cal/mole, and the pre-exponentials, equal to 3.4 · 10−11 and 0.9 · 10−11, respectively, were determined.
-
3.
There are two main directions of the reaction of oxygen atoms with methane, firstly, the formation of CH2 and H2O, and secondly, the formation of CH2O and H2.
-
4.
The main direction of the reaction of oxygen atoms with ethane involves the rupture of the C-C bond and the formation of CH2O, H2, and CH2.
