WebEquation 2 is used for diffusion in liquid and equation 3 is used for diffusion in gas. The two above equations may be used to describe any process where the bulk contribution term is zero (as equimolar counter diffusion, diffusion of solute through a solid, diffusion through stationary liquid). Concentration profile WebJan 10, 2024 · A concentration gradient occurs when a solute is more concentrated in one area than another. A concentration gradient is alleviated through diffusion, though membranes can hinder diffusion and maintain a concentration gradient.
