The aim of this analysis is to examine theoretically the mixed convection flow of an incompressible and electrically conducting viscous fluid via an infinite vertical porous plate. This research is unique in that it examines the effects of a magnetic field, Soret, heat source, chemical reaction, and Joule heating on heat and mass transmission. The mathematical model regulating the flow has been developed using partial differential equations and then converted via proper similarity transformations to a system of ordinary differential equations containing the momentum, energy, and concentration equations. Though several hypotheses have been advanced to explain the idea of boundary layer flow, the present analysis’s use of the bvp4c scheme suggests excellent agreement with the results of a previously published data in the limiting sense. Graphs and tables illustrate the numerical results of the solutions for flow field, temperature, and species concentration, furthermore the coefficient of friction factor, heat, and mass transfer characteristics. The range of parameters selected is as follows: Gr = Gm [0.1 − 3], M [1–2], χ = [ 0.1 - 0.5 ] , Ec [0.01–0.1], N [1 = 3], Pr [0.71–3], R [0.2–1], δ [0.5–3], Sc [0.22–0.61], and Sr [0.1–0.5]. The novel result shows among the major finding that velocity and concentration are decreasing while increasing values of Soret number.
