WebRate of diffusion is influenced by both temperature and molecule size. temperature but not molecule size. Solution properties Graham later studied the diffusion of salts into liquids and discovered that the diffusion rate in liquids is several thousand times slower than in gases. WebThe diffusion rate depends on several factors: the concentration gradient (the increase or decrease in concentration from one point to another); the amount of surface area available for diffusion; and the distance the gas particles must travel. ... Although diffusion and effusion rates both depend on the molar mass of the gas involved, their ... WebFeb 16, 2024 · Mass of Particle: Heavier particles will move more slowly and so will have a slower rate of diffusion.
