Ramakoteswara Rao Journal on Future Engineering and Technology 2230 – 7184 8 3 35 40 MHD, Free convection, Chemical Reaction, Mass Transfer This paper deals with the numerical study of an unsteady MHD free convection and mass transfer flow of dissipative fluid past an infinite vertical porous isothermal plate with heat generation and homogeneous chemical reaction. As the problem is governed by coupled nonlinear system of partial differential equations, exact solutions are not possible, hence explicit finite-difference method is employed. The effects of Magnetic parameter M and chemical reaction parameter K are examined on Velocity, Temperature and Concentration. The results are discussed through graphs. It is noticed that Velocity decreases with the increase in Magnetic parameter M and chemical reaction parameter K and Concentration decreases with the increase in K.
