Flow of an incompressible fluid of an infinite isothermal vertical plate is considered. The plate is exponentially accelerated in the presence of magnetic field is analysed. All partial differential equations in non-dimensional form are got from dimensional form. Laplace transform technique is used to solve all non-dimensional equations. Graphs for velocity, temperature and concentration for different thermophysical parameters like Schmidt number, chemical reaction parameter, radiation parameter, magnetic parameter, mass Grashof number, thermal Grashof number are drawn using MATLAB software. Skin friction is also depicted. Due to cooling of the plate, concentration increases for decreasing values of Schmidt number. If the intensiveness of radiation is less, then temperature increases. Velocity increases for decreasing values of radiation parameter, chemical reaction parameter, Schmidt number and magnetic parameter. Velocity also increases for the increase in values of thermal Grashof number, mass Grashof number, accelerating parameter and time. Skin friction increases for decreasing values of mass Grashof number, thermal Grashof number, Schmidt number, chemical reaction parameter and decreasing values of accelerating parameter and magnetic parameter.
