In this paper the effect of hall current, chemical reaction, radiation on a free convective flow bounded by a vertical plate embedded in a porous medium under the influence of uniform magnetic field, which is applied normal to the surface , is studied .The permeability of the porous medium fluctuates in time about constant mean. The problem is solved analytically and expressions for velocity, temperature and concentration have been obtained. The effect of permeability, magnetic number ,hall parameter , radiation parameter ,Grashof number ,modified Grashof number ,chemical reaction on velocity ,temperature and skin friction and heat transfer amplitude and phase are obtained and shown respectively with the help of figures and tables and are discussed in detail.
