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 \(\mathrm{A}-\mathrm{A}\) and \(\mathrm{B}-\mathrm{B}\) interactions
Statement II: In reverse osmosis, the applied pressure must be higher than the osmotic pressure of solution
The correct answer is
- A Both Statement-I and Statement-II are correct
- B Both Statement-I and Statement-II are not correct
- C Statement-I is correct but Statement-II is not correct
- D Statement-I is not correct but Statement-II is correct
Answer & Solution
Correct Answer
(D) Statement-I is not correct but Statement-II is correct
Step-by-step Solution
Detailed explanation
In case of negative deviations from raoult's law, the intermolecular attractive forces between \(\mathrm{A}-\mathrm{A}\) and \(\mathrm{B}-\mathrm{B}\) are weaker than those between \(A-B\) and leads to decrease in vapour pressure resulting in negative deviations. In reverse…
