Reactive diffusion
WebDec 2, 2024 · 3.2: Diffusion-controlled Reactions. Diffusion can be described as the random movement of particles through space, usually due to a concentration gradient. Diffusion is a spontaneous process and is a result of the random thermal motions between two particles. The diffusion coefficient ( D) can be solved for with Fick’s laws of diffusion ... WebDiffusion controlled reaction rates can be computed for spheres with symmetrically arranged reactive patches [9,10]. Apart from certain special symmetries, diffusion …
