An analysis has been carried out to investigate the effects of chemical reaction and radiation absorption on unsteady MHD flow with heat and mass transfer of an incompressible, viscous, electrically conducting fluid over an exponentially accelerated vertical moving plate with heat source. An exact solution for the flow problem has been obtained by solving the governing equations using Laplace-transform technique. At time  the plate is exponentially accelerated with a velocity  in its own plane. At the same time, the plate temperature and concentration levels near the plate are raised to  and  respectively. Graphical results for velocity, temperature and concentration profiles are presented and discussed.
