Given below are two statements: Statement I: Enthalpy of solution of a substance at infinite dilution is the enthalpy change when dissolved in an infinite amount of solvent such that interactions between ions are negligible. Statement II: The enthalpy of dilution of a solution is always independent of the initial concentration of the solution. In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A
    Both Statement I and Statement II are correct.
  2. B
    Both Statement I and Statement II are incorrect.
  3. C
    Statement I is correct but Statement II is incorrect.
  4. D
    Statement I is incorrect but Statement II is correct.

Correct answer · Option C

Statement I is correct but Statement II is incorrect.

Explanation

Statement I is correct by definition. Statement II is incorrect because enthalpy of dilution depends on both the original concentration and the amount of solvent added.
