Detailed explanation-1: -Surface area and thickness of the plasma membrane: Increased surface area increases the rate of diffusion, whereas a thicker membrane reduces it. Distance travelled: The greater the distance that a substance must travel, the slower the rate of diffusion.

Detailed explanation-2: -distance-if the diffusion distance is small, diffusion happens faster because the particles do not have as far to travel.

Detailed explanation-3: -An increase in temperature increases the energy of the particles, causing them to move more rapidly and increasing the rate of diffusion. On the other hand, a decrease in temperature reduces the energy of the particles and slows down the rate of diffusion.

Detailed explanation-4: -The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

Detailed explanation-5: -The rate of diffusion is inversely proportional to the size of the molecules. This means that the smaller is the size of the molecule, the higher is the rate of diffusion.
