The heat and mass transfer effects on steady two-dimensional magneto hydrodynamic flow of second-grade fluid is carried out in this study. Mathematical formulations for nonlinear flows over stretching surface in the presence of magnetic field, temperature dependent thermal conductivity, porous medium and convective boundary are carried out in Cartesian coordinate system. The model equations are determined by using fundamental laws of fluid mechanics. The governing PDEs for second-grade fluid have been derived and then transfigured into a system of nonlinear coupled ODEs via appropriate similarity transformation. The BVP is then solved by an efficient numerical scheme known as Runge Kutta Fehlberg method along with shooting technique. The outcomes are presented graphically and tabulated with the aim of illustrating the physical impacts of governing parameters on the temperature, concentration, and velocity profiles. Greater Prandtl numbers result in a decrease in temperature, while higher values of thermal conductivity and coefficient of internal heat absorption all result in an increase in temperature. Further, comparison of the results with published literature for limited cases show the validity of numerical technique.
