The heat and mass transfer characteristics of the nonlinear, unsteady, radiative MHD boundary layer slip flow of a chemically reacting fluid past an infinite vertical porous plate are taken into account in this study. The effect of physical parameters are accounted for two distinct types of thermal boundary conditions namely prescribed uniform wall temperature thermal boundary condition and prescribed heat flux thermal boundary condition. Exact solution of the governing equations for the fluid velocity, temperature, and concentration are obtained by using two term perturbation technique subject to physically appropriate boundary conditions. The expressions of skin friction, Nusselt number, and Sherwood number are also derived. The numerical values of fluid velocity, temperature, and concentration are displayed graphically whereas those of shear stress, rate of heat transfer, and rate of mass transfer at the plate are presented in tabular form for various values of pertinent flow parameters. In particular, slip parameter accelerates the fluid velocity whereas it has a reverse effect on the skin friction coefficient for both PST and PHF boundary conditions. This study is a cutting-edge simulation tool to maximize efficiency in design and operation in Naval Architecture, Offshore and Marine Engineering, as well as in the Renewable Energy sector. Results are compared with the literature in the limiting case. [ABSTRACT FROM AUTHOR]
