Assertion (A) Molality of a solution increases with temperature. Reason (R) Molality expression does not involve any volume term.

Options

  1. ABoth A and R are correct, R is the correct explanation of A .
  2. BBoth A and R are correct, R is not the correction explanation of A .
  3. CA is correct, R is not correct.
  4. DA is not correct, R is correct.

Correct answer

D. A is not correct, R is correct.

Step-by-step solution

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.
