WebThese are the factors that affect rate of Diffusion; The size of the molecule: The smaller the molecule such as gas, the faster the rate of diffusion while the larger the molecules (liquid) the slower the rate of diffusion. Concentration gradient: The greater the concentration difference, the faster the rate of diffusion. WebA liquid with smaller molecules has a lower viscosity than a liquid with larger molecules because smaller molecules slide past one another more easily.

WebDiffusion is the movement of particles from an area of high concentration to an area of low concentration. Two laws of diffusion, Graham's law and Fick's law, govern how to calculate the diffusion rate. WebFeb 2, 2011 · Diffusion is a process leading to equalization of substance concentrations in a system or establishing in a system an equilibrium concentration distribution that results from random migration of the system's elements.
