Role of the chemical mechanism in the temperature dependence of the rate of gas combustion reactions

The determining role of the kinetic mechanism in the temperature dependence of reaction rates is demonstrated. New evidence is presented to prove that the branched chain nature of gas combustion at low pressures and under isothermal conditions, discovered by N.N. Semenov, persists in combustion processes at elevated pressures under any temperature and macrokinetic conditions. It is noted that the temperature dependence of the rate constants of bimolecular reactions weakens with an increasing activation energy.
