An analytical solution of unsteady magnetohydrodynamic flow of visco-elastic fluid past an impulsively started infinite vertical plate in presence of chemical reaction, Soret and heat source/sink is studied. The governing equations are solved analytically using a regular perturbation technique. The expressions for velocity, temperature and concentration fields are obtained. With the aid of these, the expressions for the coefficient of skin friction, the rate of heat transfer in the form of Nusselt number and the rate of mass transfer in the form of Sherwood number are derived. Finally the effects of various physical parameters of the flow quantities are studied with the help of graphs and tables.
