The rate constants for both reactions were determined at a total pressure of 2 Torr from 220 to 950 K under pseudo-first-order conditions by monitoring either consumption of H atoms in excess of H2S (C4H4S) or the molecular species in excess of atomic hydrogen. For H + H2S reaction, a suggested previously strong curvature of the Arrhenius plot was confirmed: kl = 8.7 \u00d7 10\u221213 \u00d7 (T\/298)2.87 \u00d7 exp(\u2212125\/T) cm3 molecule\u22121 s\u22121 with a conservative uncertainty of 15% at all temperatures. Non-Arrhenius behavior was also observed for the reaction of H-atom with C2H4S, with the experimental rate constant data being best fitted to a sum of two exponential functions: k2 = 1.85 \u00d7 10\u221210 exp(\u22121410\/T) + 4.17 \u00d7 10\u221212 exp(\u2212242\/T) cm3 molecule\u22121 s\u22121 with an independent of temperature uncertainty of 15%.<\/jats:p>","DOI":"10.3390\/molecules28237883","type":"journal-article","created":{"date-parts":[[2023,12,1]],"date-time":"2023-12-01T04:12:56Z","timestamp":1701403976000},"page":"7883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Temperature-Dependent Kinetic Study of the Reactions of Hydrogen Atoms with H2S and C2H4S"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5383-5130","authenticated-orcid":false,"given":"Yuri","family":"Bedjanian","sequence":"first","affiliation":[{"name":"Institut de Combustion, A\u00e9rothermique, R\u00e9activit\u00e9 et Environnement (ICARE), CNRS, 45071 Orl\u00e9ans, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2439","DOI":"10.1016\/S1540-7489(02)80297-8","article-title":"Chemical kinetic modeling of the H\/S system: H2S thermolysis and H2 sulfidation","volume":"29","author":"Sendt","year":"2002","journal-title":"Proc.
