Understanding diffusion theory and Fick

WebFick’s first law of diffusion states that the rate of diffusion is proportional to the concentration gradient, or the difference in concentration between two regions. In other words, the greater the concentration gradient, the faster the rate of diffusion. This law is represented by the equation J = -D(∂C/∂x), where J is the flux of the ...
