What is Fick's Law? What influences diffusion - Answer-The molar flux due to diffusion is proportional to the concentration gradient F=kA((c1-c2)/d)) - Answer-F is rate of diffusion K is diffusion constant A is surface area for diffusion D id distance for diffusion (ex: membrane thickness) C1-C2 is difference in concentration How does the diffusion of uncharged and charged particles differ? - Answer-Uncharged particles diffuse irrespective of the concentration of each other. Charged par...
