In this paper the Thermo Diffusion and Chemical reaction effects on MHD convective flow of Visco-elastic fluid past an oscillating Porous plate in the Slip-flow regime with Heat Generation/ Absorption has been analyzed. The dimensionless governing equations are solved by using Perturbation technique. Numerical results for the velocity, temperature and concentration are shown graphically.
