The aim of the present paper is to study the effects of Dufour and Radiation absorption on an unsteady MHD free convection Casson fluid flow past an exponentially an infinite vertical plate through porous medium in the presence of thermal radiation and heat source or sink. Chemical reaction is assumed in the first order. The set of non-dimensional partial differential equations are solved analytically by using the Laplace transform technique. The influence of various non-dimensional parameters on the velocity, the temperature, the concentration, the skin friction, the local Nusselt and the Sherwood numbers are discussed and derived through graphs and tables. The velocity profile decreases with increases the values of Magnetic parameter, Radiation absorption, chemical reaction and thermal radiation. The temperature profile increases with an increase the values of thermal radiation and Dufour number.

Casson fluid, Dufour, Radiation absorption, MHD, thermal radiation and chemical reaction.
