    Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase, decrease, or prevent diffusion. The greater the concentration gradient the greater...

    Why do you think the urea was not able to diffuse through 20 MWCO? How well did the results compare with your predictions? The urea was not able to diffuse through the 20 MWCO because the membrane pores are too small and the urea molecules are large. The molecular weight of Urea is 60.07 g/mol which...
