Abstract
Using hydrogen oxidation as a model reaction, it is shown that the ignition of combustible gases upon heating in the region of atmospheric pressure is caused by a chain avalanche reinforced by self-heating of the reaction mixture, which becomes marked as combustion develops. The functional character of the temperature dependence of the rate of the chain reaction outside the region of ignition differs fundamentally from the Arrhenius law.
