Effects of chemical reaction, heat and mass transfer on MHD flow past a semi infinite plate

An approximate numerical solution for the steady MHD Slow over an infinite horizontal plate in the presence of species concentration and chemical reaction has been obtained by solving the non-linear governing equations using R. K. Gill's method. The fluid is assumed to be viscous, incompressible, and electrically conducting. A uniform transverse magnetic field is applied. It has been, observed that in the presence of chemical reaction (1) the velocity and the concentration decrease with increase of the chemical reaction parameter and vice versa, (2) the velocity decreases and the concentration, is uniform with increase of the magnetic parameter and vice versa.
