Two aqueous solutions S_(1) and S_(2) are separated by a semi-permeable membrane. S_(2)has lower vapour pressure than S_(1). Then

Answer»

more SOLVENT will FLOW from `S_(1) to S_(2)`
more solvent will flow from `S_(2) to S_(1)`
solvent from `S_(1) and S_(2)` will flow at equal rates
no flow will TAKE place.

Solution :Higher the CONCENTRATION, lower is the vapour presure. Thus, `S_(1)` has lower conc. Than `S_(2)`. More solvent will flow from `S_(1)` to `S_(2)`.
