This study investigates the radiative heat and mass transfer effects on squeezed flow of unsteady MHD second order fluid with heat source and chemical reaction. This study is carried out between two parallel circular plates under the assumption of axisymmetric squeezed flow. Similarity transform method is used to reduce the system of partial differential equation (PDE’s) into the system of ordinary differential equations (ODE’s). Advanced Collocation Method is used to find the solutions of nonlinear ordinary differential equations for velocity profile, pressure distribution, and temperature and concentration field. Effects of pertinent physical parameters on the computational results for the radial and axial velocity, pressure distrinution, and temperature and concentration profile are presented via graphs. The shear stress, heat transfer rate and mass transfer rate on the upper wall are also shown by the help of graphs.
