Heat transportation analysis subjected to porous medium consideration has increased because of industrial and engineering utilization. Typical examples comprise crude oil production, porous insulation, groundwater pollution, grain storage, mastic transport modeling, nuclear waste discarding and numerous other. The above-mentioned effectiveness of porous medium motivates us to model rate-type Maxwell material under hydromagnetic aspects. We utilized improved Darcian (Darcy–Forchheimer) expression for formulation. Consideration of improved Darcian expression modifies velocity expression through square velocity term. In addition, we accounted Robin’s condition and chemical reaction characteristics. Boundary-layer theory is employed for simplification of mathematical expressions. Dimensionless problems are treated analytically through homotopy scheme. Their significant attributes are further explored in detail. We noticed an increment in solutal and thermal fields when Biot numbers (thermal and solutal) are enhanced.
