Question
How do the following factors affect the rate of diffusion?
(i) Surface area to volume ratio
(ii) Diffusion gradient
(iii) Temperature
(i) Surface area to volume ratio
(ii) Diffusion gradient
(iii) Temperature
Answer
The rate of diffusion refers to how quickly particles or molecules spread from an area of high concentration to an area of low concentration.
i) A larger surface area to volume ratio increases the rate of diffusion by providing more surface area for molecules to move across.
(ii) A higher diffusion gradient (higher concentration difference) leads to a faster rate of diffusion by providing a stronger driving force for molecules to move.
iii) Higher temperatures increase the kinetic energy of molecules, causing them to move more quickly and leading to a higher rate of diffusion.
