ABSTRACT. The paper shows an attempt of numerical investigation on the effect of viscous dissipation and Chemical reaction on a viscous, steady and incompressible fluid over an exponentially stretching sheet within a specified boundary layer. As a formal approach, the model has been adopted with the governing equations and the simulation is carried out with the Keller Box method. The pattern or the profiles of the skin friction coefficient and the heat and mass transfer rates are achieved in execution of mathematical model have been presented in the paper. The enhancement in magnetic parameter leads to a considerable reduction in velocity and Chemical reaction parameter is predominant in controlling the profile of concentration. An increase in Eckert number is observed to cause the enhancement in the temperature profile whereas it decreases the concentration profile. The results obtained in the simulation of Keller box method are in well agreement with realistic situation of the scientific scenario.
