•Flow of second grade fluid due to a curved stretching surface with homogeneous-heterogeneous reactions is explored.•More enhancement in fluid velocity and concentration is observed for second grade fluid when compared with Newtonian fluid.•Surface drag force enhances for larger second grade fluid parameter.•Heat transfer rate is higher for Prandtl number and curvature parameter. Two-dimensional magnetohydrodynamics stretched flow of viscoelastic fluid with curved sheet is examined. Thermal radiation, Joule heating and homogeneous-heterogeneous reactions are employed to examine heat and mass transfer analysis. Suitable transformations are used to attain the nonlinear ordinary differential system. Solutions are derived numerically using quasi-linearization technique with an implicit finite difference method. Influence of certain variables on the fluid properties is discussed. Findings demonstrate that concentration of fluid is suppressed with increment in Schmidt number whereas temperature intensified for increasing radiation parameter. Fluid velocity and concentration reduces more rapidly for viscous fluid as compared to viscoelastic fluid. Also surface drag force is increasing function of second grade fluid parameter.
