NEET 2006 Chemistry question

During osmosis, flow of water through a semipermeable membrane is:-

(1)From solution having higher concentration only
(2)From both sides of semipermeable membrane with equal flow rates
(3)From both sides of semipermeable membrane with unequal flow ratesCorrect
(4)From solution having lower concentration only

Answer: (3)

Solution

A semipermeable membrane allows solvent (water) molecules to pass in both directions. Water molecules move from both sides, but the rate of flow from the dilute solution (lower solute concentration, higher solvent concentration) to the concentrated solution is greater than the reverse. The net
