Answer

Factors that affect diffusion speed: 1) Size: smaller ions and molecules diffuse faster. 2) Temperature: warmer temperatures allow for faster diffusion because of a higher level of entropy. 3) Concentration gradient: a more unbalanced gradient will have a faster rate of diffusion because it is more rushed to reach equilibrium.
