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
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
A. more solvent will flow from `S_(1) to S_(2)`
B. more solvent will flow from `S_(2) to S_(1)`
C. solvent from `S_(1) and S_(2)` will flow at equal rates
D. no flow will take place.

Correct Answer - A
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)`.
