When comparing the diffusion rate of a substance at differing concentrations within a liquid , the diffusion rate will increase with a higher concentration of the substance and the diffusion rate will decrease with lower concentration of the substance.
The higher the temperature increase the energy, the more will be the kinetic energy in the particles so that they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion .
The density of solvent increases the rate of diffusion decreases.There are some factors which affect the speed of diffusion such as extent of concentration, solvent density, temperature, pressure
