This work is focused on flow and mass transfer of a second grade fluid in a porous medium over a
nonlinear stretching sheet with chemically reactive species and suction. The governing partial differential
equations are transformed into highly nonlinear ordinary differential equations by using special
transformations, which are solved numerically using a finite difference code. Favorable comparison
with previously published work (n = 10 linear stretching sheet) is performed and the variations
of dimensionless concentration and velocity profiles as well as mass transfer characteristics with
various parameters are graphed and tabulated.
