The main goal of current research is to analyze the influences of Arrhenius activation energy in heat and mass transfer of second grade nanofluid flow. The governing equations are modeled with non–linear thermal radiation, elastic deformation of second grade nanofluid, Brownian motion, thermophoresis and Arrhenius activation energy. The momentum slip, active and passive controls of nanoparticles are assumed in the boundary. Similarity transformations, Runge-Kutta of order four and shooting methods are used to solve the governing equations. Graphical results are presented. It is found that the concentration profile augments with activation energy and decreases with exponential fitted rate. The local Nusselt number is increased with activation energy and decreased with elastic deformation and exponential fitted rate.
