This behavior of the rate constant could be explained by the fact that this reaction occurs on the surface of the reactor. However, experiments carried out under different conditions of the diffusion of reagents to the surface of the reactor showed that the reaction of the chlorine atom with hydrogen sulfide proceeds in the volume.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181325799552">Методом резонансной флуоресценции атомов хлора в проточном реакторе в диапазоне температур 273–366 K была измерена константа скорости реакций атома хлора с сероводородом, значение которой уменьшалось при увеличении температуры в реакторе. Такое поведение константы скорости можно было бы объяснить тем, что данная реакция протекает на поверхности реактора. Однако опыты, проведенные при разных условиях диффузии реагентов к поверхности реактора, показали, что реакция атома хлора с сероводородом протекает в объеме.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hydrogen sulfide</kwd><kwd>chlorine atom</kwd><kwd>resonant fluorescence</kwd><kwd>reaction rate constant</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сероводород</kwd><kwd>атом хлора</kwd><kwd>резонансная флуоресценция</kwd><kwd>константа скорости реакции.</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hansen M.H., Ingvorsen K., Jorgensen B.B. // Limn.
