Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. Once the concentrations are equal the molecules continue to move, but since there is no concentration gr… WebNov 17, 2015 · At equal temperatures, lighter particles will diffuse more rapidly than heavier particles. Diffusion is the movement of particles from where they are more concentrated …

How Does Molecular Weight Affect the Rate of Diffusion?

WebThe relationship between molecular size and the rate of diffusion is an inverse relationship; more simply put, the smaller a molecule, the faster it diffuses. Does diffusion require energy? Passive mechanisms like diffusion use no energy , while active transport requires energy to get done. http://mw.concord.org/nextgen/interactives/ text message not showing on iphoneWebDoes molecular size affect diffusion? We know that higher the molecular mass bigger is the size of the molecule. The expression for the Graham’s law of diffusion shows that the rate of diffusion is inversely proportional to the molecular mass i.e. the rate of diffusion is inversely proportional to the size of the molecule. swth token

"WebTemperature and other factors influencing the rate of diffusion.
