Soret impact of rotational action on the unsteady MHD parabolic flow across an accelerating vertical plate with constant mass diffusion and uniform temperature. The fluid under consideration conducts electricity. The solutions for the profiles of velocity, temperature, and concentration have been found using the Laplace transform method. Various graphs for parameters such as the thermal Grashof number, the mass Grashof number, the Prandtl number, the Hartmann number, the Schmidt number, the Soret number, the time of magnetic field, and the acceleration parameter are used to describe the findings obtained. The velocity is expected to expand as the mass Grashof or heated Grashof number is estimated to grow. It is also verified that the velocity increases as the magnetic field strength decreases.
