Consider a Microporous Membrane That Separates a Solution on the Left

question 5

Multiple Choice

Consider a microporous membrane that separates a solution on the left with concentration CL from a solutio n on the righ t at C _R. The permeability for the solute, p > 0. If C_L > C _R, the presence of pressure-driven flow from right to left should

• A) Increase the net flux of solute from left to right by solvent drag.
• B) Increase the net flux of solute from right to left by solvent drag.
• C) Decrease the net flux of solute from left to right by solvent drag.
• D) Decrease the net flux of solute from right to left by solvent drag.
• E) Not affect net flux of solute from left to right.
