Factors which affect rate of diffusion are:
(1) The Gradient of concentration: Rate of diffusion affected by gradient of concentration in positive manner like with increases in rate of diffusion concentration gradient increases across the barrier.
(2) Permeability of membrane: Permeability of membrane increases with increase in Rate of diffusion which helps in diffusion of substance inside the cell
(3) Temperature: With the increase in temperature rate of diffusion increases because high temperature makes cells more permeable.
(4) Pressure: In cell diffusion takes place from high partial pressure to low partial pressure therefore pressure also affects the rate of diffusion.Answered by Abhisek | 11 months ago
