Abstract: An analys is was developed in order to study the unsteady free convection flow of an incompressible, visco-elastic fluid on a continuously moving vertical porous plate in the presence of a firs-torder chemical reaction. The governing equations were solvednumerically using an implicit finite difference technique. The selected numerical method was validated by comparing the results with the analytical solutions. Numerical results for the details of the velocity profiles which were shown on graphs were presented. A parametric study was performed to illustrate the in fluence of the visco-elastic parameter, dmiension less chemical reaction parameter and plate moving velocity on the steady state velocity profiles, the tmie dependent friction coefficient, Nusselt number and Sherwood number.
