An analysis is presented to investigate the effects of chemical eaction, thermal stratification Sort number and Dufour number for magnetohydrodynamic free convctive heat and mass transfer of a viscous and incompreessable and ellectrically conduction flluid in vertical strechinf surface emmbeded in a saturated porors media . The govrning patail eqs have benn transformed by a simmialrity transformation into a system ordinary differentional equation which are solved numerically using a fourth order Rung Kutta schem with the sooting method . the results obtained show that the field is influnced apprecaciaply by the presence of chemical reaction , thermal statification, Sort number, Dufour number and magnetic field.
