Given below are two statements. Statement I: Liquids A and B form a non-ideal solution with negative deviation. The interactions between A and B are weaker than A - A and B - B interactions Statement II: In reverse osmosis, the applied pressure must be higher than the osmotic pressure of solution The correct answer is

Step-by-step solution

In case of negative deviations from raoult's law, the intermolecular attractive forces between A - A and B - B are weaker than those between A-B and leads to decrease in vapour pressure resulting in negative deviations. In reverse osmosis the applied pressure must be higher than the osmotic pressure of solution. Hence Statement I is incorrect but II is correct.
