Thermo diffusion and chemical effects on heat transfer in MHD mixed convection flow and masstransfer past an infinite vertical plate with Ohmic heating and viscous dissipation have beenstudied. Approximate solutions have been derived for velocity, temperature, concentration profiles,skin friction, rate of heat transfer and rate of mass transfer using perturbation technique. Theobtained results are discussed with the help of graphs to observe the effect of various parameterslike Schmidt number (Sc), Prandtl number (Pr), Magnetic parameter (M),Soret number (So) andchemical parameter (K), taking two cases viz. Case I: when Gr > 0 (flow on cooled plate) and CaseII: Gr < 0 (flow on heated plate). Thermal diffusion causes both the fluid velocity and temperature tofall due to the presence of the chemical effect. Velocity and temperature profiles are higher formercury than electrolytic solution. Soret effect increased the concentration of the fluid while chemicaleffect decreased.Keywords: Chemical effect; thermo diffusion; magnetic field; heat-mass transfer.DOI: 10.3329/jname.v6i2.3761
