By what factor would the rate of diffusion change if membrane thickness doubled?
nasty-shy [4]

Tripling  of the diffusion rate would correspond to a factor 3.

<h3>What are the factors which affects the rate of diffusion ?? </h3>

Substances diffuse when they travel passively from one area of high concentration to another area of lower concentrations . During cellular transport in plants, diffusion of chemicals is crucial. The concentration gradient, membrane permeability, temperature and pressure all have an impact on the rate of diffusion . As long as there is a difference in  a substance concentration on either side of a barrier, diffusion will occur.

So by tripling the diffusion rate it would change to factor of 3.
