We have considered the unsteady an incompressible MHD rotating free convection flow of Visco-elastic fluid with simultaneous heat and mass transfer near an infinite verticaloscillating porous plate under the influence of uniform transverse magnetic field and taking hall current into account. The governing equations of the flow field are solved by a regularperturbation method for small elastic parameter. The expressions for the velocity, temperature, concentration have been derived analytically and also its behaviour iscomputationally discussed with reference to different flow parameters with the help of graphs. The skin friction on the boundary, the heat flux in terms of the Nusselt number, andthe rate of mass transfer in terms of the Sherwood number are also obtained and their behaviour discussed.
