i just answered a hw question that i was a little confused on. i answered it but am not fully sure if it's correct. so can you take a look at check if my answer is correct and if it's not, then a explaintion would be helpful.
Would you expect water molecules to move faster when there is a HIGH concentration gradient or a LOW concentration gradient?
Water molecules would move faster when there is a high concentration gradient because the pressure for the molecules in the high concentration to reach equilibrium increases since there are more molecules there than in the low concentration. So as the molecules move down the concentration gradient faster to equalize the concentration on both sides due to the increased pressure, the rate of diffusion increases.
