The effects of convective boundary conditions on the flow of a viscous fluid through a porous sheet that is expanding exponentially are studied in this study, along with additional factors such as heat absorption, viscous dissipation, thermophoresis, chemical reactions, and others. The numerical solutions to the governing equations are evaluated using the bvp4c technique in conjunction with similarity requirements. The effect of different parameters on different physical variables are depicted using graphs. The fluid's velocity increases with the increase in thermophoretic parameter. The temperature profile decreases with the rise in Grashof number and Schmidt number. While the concentration profile escalates with the rise in Schmidt number. Many real-world situations involve the co-existence of thermophoresis, viscous dissipation, chemical processes, heat absorption etc.
