L B P Two containers (A and B) are connected using a pipe (length:L=20cm, diameter: D). Both A and B are filled with stagnant acetic acid aqueous solution. In container A, acetic acid concentration is 2.0 mol/L. In container B, acetic acid concentration is 0.1 mol/L. The whole system is at the same temperature and pressure.

What is the estimated flux of acetic acid if the system temperature is 40C (assuming n in Stocks-Einstein equation is constant from 0C to 40C)(5 pt) 4. What if the pipe is loaded with a porous inert catalyst (no reactions), what is the flux of acetic acid at 25C? The parameters for the porous material (c=0.35, tortuosity(t)=4.2) (5 pt)
