In this paper, the groundwork of some thermophysical properties of higher-order chemical processing and dissipation of viscous on nanofluid along with a continuously stretching porous sheet is taken. The porous medium is considered with two space coordinates, laminar, time-invariant, MHD incompressible Newtonian nanofluid. The equations are framed to govern the fluid flow as coupled equations involving nonlinear partial derivatives. The impacts of electric and magnetic fields on nanofluid with viscous dissipation in the presence of higher-order chemical reaction, analyzing conservation of momentum and energy, is the novelty of the problem. The level of raising thermal conductivity and the output of transferring the heat on nanofluid is observed. Finally, the governing equations involving partial derivatives have complied with nonlinear ordinary differential equations. The transformations are subjected to the similarity variable used to solve these equations. Approximate solutions are obtained using a numerical method of the Runge-Kutta-Felburg method with shooting technique. The effects of emerging parameters Kr,Er,λ,Nt,δ,Nb are porous, electric, mixed convection, thermophoresis, chemical process and, Brownian motion, and non-dimensional numbers such as Hartmann, Prandtl, Schmidt, and Eckert are extensively explained. The electrically conducting nanofluid flow for velocity fluid, temperature fluid and, nanoparticles concentration volume fraction fluid with transferring heat, Nusselt, and transferring mass, Sherwood number are examined with graphical representation. The Lorentz resistive force due to the applied strength of electric develops the thickness of boundary layers of momentum and thermal regions. This helps to cool the electronic systems and radiators. The dimensionless Nusselt number diminishes with various values of thermophoresis and Brownian motion parameters as a dependent function of Hartmann, electric number, and homogeneous chemical reaction parameter.
