The steady two-dimensional magnetohydrodynamic heat and mass transfer free convection flow of a viscous incompressible fluid near an isotherm al linearly stretching sheet in the presence of a uniform magnetic field with heat generation is considered. The equations governing the flow, temperature and concentration field are reduced to a system of coupled non-linear ordinary differential equations. These non-linear differential equations are integrated numerically by using Nachtsheim-Swigert shooting iteration technique along with sixth order Runge-Kutta integration scheme. Finally the effects of the pertinent parameters which are of physical and engineering interest are examined both in graphical and tabular form.
