An analytical study is performed to investigate radiative heat and mass transfer effects on unsteady MHD free convective fluid flow past an inclined plate with variable temperature and mass diffusion through porous medium in the presence of transverse applied magnetic field. The fluid considered here is gray, absorbing/emitting radiation but a non-scattering medium. At time t > 0, the plate temperature and concentration levels near the plate are raised linearly with time t. The governing equations are solved in closed form by the Laplace transform technique. The velocity, temperature, concentration, the rate of heat transfer and the rate of mass transfer are studied through graphs while the numerical values of skin-friction is presented in tabular form for different physical parameters like radiation parameter (R), magnetic field parameter (M), Schmidt parameter (Sc), Prandtl number (Pr), thermal Grashof number (Gr), mass Grashof number (Gm), accelerated parameter (a), inclination parameter () and time (t).
