Write how the following affect the rate of diffusion a different gradients be temperature c size of molecules d surface area to volume ratio
a) Concentration gradients: The rate of diffusion is directly proportional to the concentration gradient. The higher the concentration gradient, the faster the rate of diffusion.
b) Temperature: Higher temperatures increase the rate of diffusion because molecules have more kinetic energy and move faster.
c) Size of molecules: Smaller molecules diffuse faster than larger molecules, as smaller molecules have a lower mass and therefore move faster.
d) Surface area to volume ratio: A higher surface area to volume ratio leads to a faster rate of diffusion. This is because there is more surface area for the molecules to diffuse across, which increases the rate of diffusion.
