The present investigation explores the unsteady magnetohydrodynamic (MHD) free convective oscillating flow of an optically thin incompressible viscous fluid embedded in two parallel porous walls under the influence of an externally applied transverse magnetic field with a chemical reaction. The radiative heat flux and heat absorption effects are considered. The governing equations are solved for the velocity, temperature, and concentration distributions making by making use of the Laplace transformation methodology. The impacts of a combined of relevant flow parameters on concentration, temperature, and velocity distribution are discussed with pertinent non-dimensional parameters. The analytical solutions for the governing equations are found by utilization of Laplace transformation methodology. The velocity, temperature and concentration profiles are analyzed. The expression for the velocity, the concentration, the shear stress and the rate of heat and mass transfer are derived and are analysed for different variations of the governing parameters.
