The convection heat and mass transfer in a hydromagnetic flow of a second grade fluid past a semi-infinite
stretching sheet in the presence of thermal radiation and thermal diffusion are considered. The governing
coupled non-linear partial differential equations describing the flow problem are transformed into non-linear
ordinary differential equations by method of similarity transformation. The resulting similarity equations are
solved numerically using Runge–Kutta shooting method. The results are presented as velocity, temperature
and concentration fields for different values of parameters entering into the problem. The skin friction, rate of
heat transfer and mass transfer are presented numerically in tabular form. In addition, the results obtained
showed that these parameters have significant influence on the flow, heat and mass transfer
