---

The aim of this work is to analytically present coupled heat and mass transfer characteristic of mixed convection boundary layer flowing on horizontal surface embedded in a porous medium with exponentially decaying internal heat generation (IHG) and internal mass generation (IMG) over specific component in the presence of thermal radiation and chemical reaction, respectively. Corresponding similarity solutions are used to reduce the governing partial nonlinear differential equations to three ordinary differential equations for the dimensionless stream function, temperature, and concentration with the following parameters: mixed convection parameter, exponent of x, chemical reaction parameter ,radiation parameter R , and Lewis number Le . Media with and without IHG and IMG are compared in context with the help of graphs and tables. Computations are performed with a system of parameters using built-in codes in Maple. The influences of these parameters on velocity, temperature and concentration profiles, and Sherwood and Nusselt numbers are thoroughly compared and graphically illustrated.
