Click to see full answer. Just so, what factors affect rate of diffusion?Many factors can affect the rate of diffusion, including, but not limited to, concentration gradient, size of the particles that are diffusing, and temperature of the system.Additionally, what happens to the diffusion rate as the distance increases? Diffusion Distance The rate of diffusion is inversely related to the distance through which the material is diffusing. That is, smaller distances result in faster diffusion rates and larger distances result in slower diffusion rates. Furthermore, what are five factors that affect the rate of diffusion? Several factors affect the rate of diffusion of a solute including the mass of the solute, the temperature of the environment, the solvent density, and the distance traveled.What affects the rate of osmosis?Concentration gradient – The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent. Light and dark – They are also factors of osmosis; since the brighter the light, the faster osmosis takes place.
