This study deals with the unsteady flow of an Eyring-Powell fluid induced by an oscillatory stretching surface in presence of chemical reaction. The elastic sheet is stretched periodically back and forth in its. fawn plane. The equations governing the flow are derived employing fundamental law of mass, momentum and diffusion. The independent variables in the governing equations are reduced by using dimensionless variables which are solved by using two different techniques, namely, homotopy analysis method and an implicit finite difference scheme. Solutions obtained by both methods are compared and found in excellent agreement. The physical variables such as longitudinal velocity component and mass concentration are examined in detail for various values of the parameters of interest.
