Abstract: The three-dimensional boundary layer flow of an elastico-viscous fluid over a stretching surface was looked at. Velocity of the stretching sheet was assumed to be time-dependent. Effect of mass transfer with higher order chemical reaction was further considered. Computations were made by homptopy analysis method(HAM). The convergence of the obtained series solutions was explicitly analyzed. The variations of embedding parameters on the velocity and concentration were graphically discussed. Numerical computations of surface mass transfer were reported. Comparison of the present results with the numerical solutions was also seen.
