The present paper deals analytically the influence of chemical reaction on unsteady MHD free convective mass transfer flow of a viscous incompressible fluid past an infinite oscillating plate in presence of thermal radiation and thermo - diffusion (Soret) effects. Cogly-Vincentine-Gilles equilibrium approximate model is incorporated in the energy equation and the effect of first- order homogeneous chemical reaction has also been considered in the species concentration equation. The governing system of partial differential equations subject to favorable boundary conditions is solved in closed form by using one-sided Laplace transform technique. The influence of various pertinent parameters on the velocity, concentration, skin-friction, Nusselt and Sherwood numbers of thermally assisting, chemically reactive flow has been investigated through graphs and tables. It is observed that, the first order chemical reaction reduces the fluid velocity, plate friction and fluid concentration but enhances the mass transfer rate. It is also observed that, the fluid velocity, skin-friction and Nusselt number increase with rise in parametric values of Soret number
