The effect of a chemical reaction on the free convection flow of a viscous incompressible conductive micropolar fluid from a radiative vertical porous plate with a uniform surface temperature, uniform rate of suction or injection and uniform magnetic field is investigated. The Rosseland diffusion approximation is used to describe the radiative heat flux in the energy equation. As the micropolar parameter increases the temperature, concentration and microrotation increase while the velocity decreases for the suction and injection case and increasing the chemie al reaction parameter decreases the velocity, concentration and microrotation for the suction and injection case while the temperature increases with the increasing of the chemical reaction parameter.
