An enthalpy diagram reflecting the PES of this reaction system is constructed. It is shown that the addition of a hydrogen atom to ethylene with the formation of an ethyl radical occurs through the formation of a van der Waals complex. The diagram of enthalpies of monomolecular reactions of decomposition and isomerization of the ethoxyl radical is presented in detail, and a conclusion is made about the probability of their occurrence. The global PES minimum of the system describing the sequential addition of hydrogen and oxygen atoms to ethylene is the hydroxyethyl radical. Intermediates CHCH2OH and CH2OCH2 are localized on the PES of the C2H4 + O system and possible pathways for their further transformation are analyzed. The data obtained make it possible to estimate the ranking of individual elementary reactions in the processes of combustion and oxidation of hydrocarbons and the probabilities of various directions for the transformation of chemical species in the studied systems</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181323404224">Поверхность потенциальной энергии (ППЭ) реакционной системы H + O + C<sub>2</sub>H<sub>4</sub>, которая играет важную роль в окислительной конверсии углеводородов в целом, была теоретически исследована с использованием различных квантовохимических методов.

Получены данные относительно последовательности энергетических уровней образования этоксильного радикала, представлена детальная диаграмма энтальпий мономолекулярных реакций его распада и изомеризации, сделан вывод о вероятности их протекания.
