ABSTRACT=<p>This analysis addresses the influence of activation energy on the MHD flow of second-grade nanoliquid over a convectively heated curved stretched surface. The impact of heat generation/absorption, thermophoresis, and Brownian motion are also incorporated. This current study in addendum reveals the solution narrating the nanofluid flow behaviour of the stretched curve to better the performance of the system. Hence, the mathematical construction of governing partial differential equations (PDEs) is transmitted into nonlinear ODEs by employing appropriate transformations. The attained ODEs are conducted numerically <italic>via</italic> ND-Solve. It is consequential to report that fluid velocity and temperature fields significantly rise with concurrent enhancing values of the fluid parameter and curvature parameter. Moreover, the concentration field enhances considering the energy activation variable and suppresses with the reaction rate constant while thermophoresis escalates the temperature distribution as the Nusselt number lowers with a stronger internal heat source parameter Q.</p>
