Influence rate of diffusion. Fick's Laws of Diffusion, a cornerstone in understanding this phenomenon, Understand that diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, driven by the concentration gradient. It refers to the difference in the concentration For our purposes, when you want to predict relative rates of movement of gases, you can start with the effusion/diffusion equation. Temperature impacts diffusion rate because higher The rate of diffusion is influenced by several factors, including the concentration gradient, temperature, the size of the particles, and the medium through which diffusion occurs.
