theoretical steady of two-dimensional and MHD couple stress fluid flow over a linearly stretching sheet is investigated with the effects of thermal\udradiation, internal heat generation and homogeneous chemical reaction of first order. The governing equations of continuity, momentum, energy and\uddiffusion for this boundary layer flow are transformed into one set of coupled non-linear ordinary differential equations using the local similarity\udtransformation and are then solved using the fourth-order Runge-Kutta method along with the shooting technique. The effects of the couple stress\udparameter (\udS\ud), Magnetic parameter (\udM\ud) and chemical reaction parameter (\udCr\ud) are presented through the graphical illustrations. It has been found\udfrom the results that the temperature of the couple stress fluid is enhanced due to increases in\udPr,Ec,M\udand\udQ\udbut decreased with\udR\udand\udS\ud. Increase\udin the couple stress parameter (\udS\ud) enhances the flow velocity but enhance in the magnetic field (\udM\ud) reduces the flow velocity
