The main purpose of this work is to investigate the porous medium and diffusion thermo effects on unsteady combined convection magneto hydrodynamics boundary layer flow of viscous electrically conducting fluid over a vertical porous surface in the presence of first order chemical reaction and thermal radiation. The slip boundary condition is applied at the porous surface. A uniform Magnetic field is applied normal to the direction of the fluid flow. The non-linear coupled partial differential equation are solved by perturbation method and obtained the expressions for concentration, temperature and velocity fields. The rate of mass transfer in terms of Sherwood number h , the rate of heat transfer in terms of Nusselt number Nu and the Skin friction coefficient Cf are also derived. The Profiles of fluid flow and derived quantities for various values of physical parameters are presented and analyzed.
