An analytical study for the problem of unsteady mixed convection with thermal radiation and first-order chemical reaction on magneto hydrodynamic boundary layer flow of an electrically conducting visco-elastic fluid past a vertical permeable plate has been investigated. Slip boundary layer condition is applied at the porous interface. The classical model is used for studying the effect of radiation for optically thin media. The perturbation scheme has been used to solve the problem. Analytical expressions for dimensionless velocity, temperature, concentration fields, skin friction co-efficient, rate of heat transfer and Sherwood number have been obtained. The profiles of the velocity and skin friction have been presented graphically for different values of the visco-elastic parameters with the combination of the other flow parameters encountered in the problem under investigation.
