· Rate of Diffusion ∝ Surface area x Concentration gradient/Thickness of membrane. This means that the diffusion rate gets double if the surface area or concentration gradient is doubled and the thickness of the membrane is halved. History and Background. They were developed by Adolf Fick in 1855 to mathematically represent the rate of diffusion of dissolved gases across membranes.
