The mixture is described by the Simple Reacting Spheres (SRS) kinetic model which treats both elastic and reactive collisions as hard spheres type and introduces a ‘‘correction’’ term in the elastic operator in order to prevent double counting of the events in the collisional integrals. We use the Chapman–Enskog method, at the first-order level of the Enskog expansion, to determine the non-equilibrium solution to the SRS system in a chemical regime for which both elastic and reactive collisions occur with comparable characteristic times. We then determine the transport coefficients and focus our analysis on the evaluation of those coefficients associated with the reaction rate and the shear viscosity. Our numerical evaluation of the transport coefficients allows for the investigation of their behaviour in a suitably chosen parametric space with an opportunity to check how these coefficients are influenced by the chemical reaction and by the ‘‘correction’’ term proper of the SRS model.The paper is partially supported by the Portuguese Funds FCT, Portugal Project UID/MAT/00013/2013.info:eu-repo/semantics/publishedVersionElsevierUniversidade do MinhoCarvalho, FilipePolewczak, JacekSilva, Adriano W.Soares, Ana Jacinta2018-092018-09-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/1822/54577eng0378-437110.1016/j.physa.2018.03.082https://www.sciencedirect.com/science/article/pii/S0378437118304023info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-07-21T12:32:24Zoai:repositorium.sdum.uminho.pt:1822/54577Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T19:27:44.702019Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
