This paper deals with a steady two-dimensional magnetohydrodynamic stagnation-point flow, heat and mass transfer of a viscous fluid over a stretching sheet in the presence of thermal radiation, heat generation/absorption and chemical reaction of order n in a Darcian porous medium. The basic boundary layer equations for flow, heat and mass transfer describing the problem are nonlinear partial differential equations. These equations are transformed into coupled nonlinear ordinary differential equations by means of similarity transformation and are then solved numerically using a suitable finite difference technique. The finite difference schemes are employed to linearize the governing ordinary differential equations and the resulting nonlinear algebraic equations are solved using modified Newton’s method. The influences of different embedded flow parameters such as permeability, magnetic field, stretching ratio, rate of chemical reaction, order of chemical reaction and thermal radiation parameters as well as Prandtl and Schmidt numbers on velocity, temperature and species concentration profiles are presented in graphical forms. The local skin-friction, Nusselt and Sherwood numbers are tabulated and discussed in details.
