An analytical study was performed to study effects of thermo-diffusion andchemical reactions on a three-dimensional MHD mixed convective flow ofdissipative fluid along an infinite vertical porous plate with transversesinusoidal suction velocity. The parabolic partial differential equationsgoverning the fluid flow, heat transfer, and mass transfer were solved usingperturbation technique and the expressions for velocity, temperature, andconcentration distributions were obtained. Expressions for skin friction at theplate in the direction of the main flow, rate of heat transfer, and mass transferfrom the plate to the fluid were derived in a non-dimensional form. Velocity,temperature, concentration, amplitudes of the perturbed parts of skin friction,rate of heat transfer, rate of mass transfer, and skin friction at the plate arepresented in graphs and effects of various physical parameters like Hartmannnumber M, Prandtl number Pr, Reynolds number Re, Schmidt number Sc, Soretnumber So, Grashof number for heat transfer Gr, Grashof number for masstransfer Gm, and chemical reaction parameter Kr on the above flow quantitieswere analyzed and then the obtained results were physically interpreted
