Abstract:

The relationship between activation energy for diffusion, ED and the BET heat of sorption, E1, was determined from literature data for maize, rice, sorghum, soybean and wheat and gave ED/E1= 0.5. Given that ED < E1, diffusion was interpreted in terms of a mechanism involving the hopping of water molecules from one adsorption site to another. Copyright © 1989, Wiley Blackwell.
