A magnetohydrodynamic convective unsteady flow past a uniformly accelerated infinite isothermal vertical plate in the presence of variable mass diffusion is analyzed using the Laplace transform technique. The plate temperature is raised to [...] and the concentration level near the plate is raised linearly with time.The velocity profiles are studied for different physical parameters such as the magnetic field parameter, thermal Grashof number, mass Grashof number and time. It is observed that the velocity increases with increasing values of the thermal Grashof number or mass Grashof number. It is also observed that the velocity increased with decreasing the magnetic field parameter.
