The present study investigates solution to the problem of magnetohydrodynamics free convective flow past an inclined porous plate in presence of the heat source, Soret effect, Dufour effect and chemical reaction. To analyze the flow model, we transform it into a system of partial differential equations. We then employ the bvp4c method in MATLAB to obtain numerical solutions for this system. Numerical results show that the chemical reaction, thermal radiation, angle of inclination, Soret and Dufour effects possess a major impact on the heat and mass transfer of the fluid. The results of this study could be relevant in the fields of chemical industries, chemical engineering, and petroleum engineering. Velocity, temperature and concentration distribution are presented graphically for various emerging physical parameters like Soret number, Dufour number, Prandtl number, radiation and the heat source.
