Abstract: Activation energy is an important role in chemical reaction because the factor is very useful in the application of geothermal reservoir engineering, oil emulsions and water mechanics. Based on this observation investigated the role of activation energy and chemical reaction in viscoelastic liquid past a stretching surface. Buongiorno’s model is used in this study. Nonlinear thermal radiation is incorporated in the energy equation. Convective type boundary condition is implemented. Mass transport performance is analyzed through zero normal flux condition. Solution of the nonlinear equations is obtained by adopting RKF method of fourth and fifth order. The dimensionless numbers on velocity curve, temperature curve and nanoparticle volume concentration curve is elaborated. Further engineering curiosity of drag coefficient, local Nusselt and Sherwood numbers are tabulated, depicted and interpreted. It is noted that rise of reaction rate and activation energy decelerates the local Nusselt number and accelerates the local Sherwood number.
