We're learning about flux and Fick's law and there's one point I'm having trouble understanding. Assuming we have a higher concentration of a species on one side of a membrane, I understand that increasing the concentration will increase the flux (net particle movement/(time*area)). We were told as well that increasing the concentration also decreases the time it takes to reach equilibrium. Why would that be?
Rephrased: If you have 10 particles on one side of the membrane and 0 on the other, it takes X amount of time to reach equilibrium (~ 5 particles on each side). If you have 10 million particles, why would it take <X amount of time to reach equilibrium (~5M particles on each side).
