The aim of the present work is to analyze the characteristics of magnetohydrodynamic free convective radiating fluid past a porous plate in the presence of thermal diffusion and heat source/sink along with variable temperature and concentration. An exact solution has been employed by usual Laplace transform technique. The effects of diverse parameters on velocity, temperature and concentration are discussed through graphical representations. Also the variations in shear stress, rate of heat transfer and rate of mass transfer under the influence of some parameters are discussed with the help of tables. In the presence of heat source the fluid velocity and temperature increases whereas the concentration decreases. Increasing values of Soret number serves to enhance the velocity and species concentration but an opposite nature is seen in the case of Schmidt number.
