Our key objective in the present work is to elaborate the concept of study of the magnetohydrodynamic flow of non-Newtonian incompressible fluid obeying (Walters' liquid) model with mass and heat transfer over an infinite porous horizontal stretching sheet under radiation, heat generation (absorption) and chemical reaction. The governing differential equations which describe the motion of the problem are converted into dimensionless formulas by using perturbation technique. The effects of the elasticity, porosity parameter, heat generation, radiation parameter, Chemical reaction parameter effect and magnetic interaction parameter, Prandtl and Schmidt numbers on the velocity, temperature and concentration distributions have been discussed and illustrated graphically.
