👉 Autodiffusion is a process in which a substance diffuses away from an area of high concentration into a region with lower concentrations. This can be due to a variety of factors, such as diffusion barriers or changes in temperature. In chemistry and physics, it refers to the movement of molecules or particles through a medium, where they diffuse out of one direction (high concentration) towards another (low concentration). The process is typically characterized by the presence of solute-solute interactions that cause the dispersion
