The Soret and Dufour effects on unsteady mass transfer flow through a highly porosity bounded by a vertical infinite moving plate in the presence of the heat generation and chemical reaction have been studied. The Rosseland approximation has been used to describe the radiative heat flux in energy equation. The governing equations are solved numerically by using Galerkin finite element method. The effects of various parameters on the velocity, temperature and concentration fields have been examined with the help of graphs.
