Assertion (A) Molality of a solution increases with temperature.
Reason (R) Molality expression does not involve any volume term.
- A Both \(A\) and \(R\) are correct, \(R\) is the correct explanation of \(A\).
- B Both \(A\) and \(R\) are correct, \(R\) is not the correction explanation of \(A\).
- C A is correct, \(\mathrm{R}\) is not correct.
- D A is not correct, \(R\) is correct.
Answer & Solution
Correct Answer
(D) A is not correct, \(R\) is correct.
Step-by-step Solution
Detailed explanation
Assertion is incorrect while Reason is correct. Molality is defined in terms of the solvents mass, not by its volume, thus temperature does not change the molality of a solution.
