Which of the following statements is false?

Question

Which of the following statements is false? (A) Units of atmospheric pressure and osmotic pressure are the same (B) In reverse osmosis, solvent molecules move through a semipermeable membrane from a region of lower concentration of solute to a region of higher concentration (C) The value of molal depression constant depends on nature of solvent (D) Relative lowering of vapour pressure, is a dimensionless quantity

Tardigrade Admin · Accepted Answer

If a pressure higher than the osmotic pressure is applied on the solution, then reverse osmosis takes place i.e., the solvent will flow from the solution (i .e., high cone, of solute) into the pure solvent (i.e., low cone, of solute) through the semipermeable membrane.
