This study investigates the impact of MHD, variable viscosity, thermal-diffusion, and diffusion-thermo effects with the heat source on mixed convection of heat and mass transfer over an accelerating surface. The physical problem's governing equations involve a coupled non-linear partial differential equations, which are transformed to a coupled non-linear ordinary differential equations using a suitable similarity transformation. Numerical computation using shooting technique is adopted to study the physical characteristics of velocity, temperature, and concentration for various values of non-dimensional parameters like thermal diffusion parameter, diffusion-thermo parameter, viscosity parameter, Prandtl number, and strength of the magnetic field are involved in the problem. The obtained numerical results are found to be a good agreement with the earlier works.
