Influence of radiation and chemical reaction on MHD flow past a moving plate with Hall current is studied here. Earlier, we (2016) have studied unsteady MHD flow in porous media over exponentially accelerated plate with variable wall temperature and mass transfer along with Hall current. To study further, we are changing the model by considering radiation and chemical reaction on flow, and changing geometry of the model. Now, we are taking the plate positioned vertically upward. Laplace method is used to solve the flow model. The results obtained have been analyzed with the help of graphs drawn for different parameters. The numerical values obtained for the drag, Sherwood and Nusselt numbers at boundary have been tabulated. Here too, the results are found to be in agreement with the actual flow.
