This study develops a model to analyze the effect of chemical reaction in a Darcy-Forchheimer nanofluid mass and heat transfer flow over a nonlinearly extending surface with the effect of non-uniform magnetic force. Further, it is presumed that the fluid is viscous and incompressible. A powerful tool of similarity variables is exploited to transform the governing flow model PDEs into ordinary ones, which are then solved with the aid of the Successive Over Relaxation (SOR) technique using MATLAB software. Our outcomes are linked to those presented in the earlier research works in the literature and found to be in good agreement with them. The effects of different involved parameters are examined and visualized through tables and diagrams. From the current investigation, it is revealed that the chemical reaction enhances the mass transfer rate, whereas the Forchheimer parameter tends to devaluate the mass and heat transport rate on the surface. The magnetic and porosity parameters tend to increase the skin friction. The present results can be applied with caution to thermal control systems.
