This article emphases on the study of the flow, heat and mass transfer from an exponentially stretching surface in a viscous fluid with heat source. The viscosity and thermal conductivity are assumed to vary as a linear function of temperature. The equations of the flow are converted into ordinary differential equations by utilizing the similarity transformations. The resulting non-linear system is solved applying the Successive linearization method along with the Chebyshev collocation method. The physical quantitites of the flow problem are computationally analyzed and exhibited via graphs. It is noticed that the rate of heat transfer increased with raise in Biot and decreased with increase in the value of thermal conductivity and heat source parameters. While, the rate of mass transfer increased with increase in the values of Biot, thermal conductivity and heat source parameters and skin-friction is increasing with viscosity parameter and decreasing with thermal conductivity and heat source parameters.
