Assertion: An ideal solution obeys Henry...

Assertion: An ideal solution obeys Henry's law.
Reason: In an ideal solution, solute-solute as well as solvent solvent interactions are not similar to solute-solvent interaction.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true, but reason is not the correct explanation of assertion.

C

If assertion is true, but reason is false.

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
D
An ideal solution obeys Raoult.s law. In an ideal solution, it takes exactly the same amount of energy for solvent molecule to break away from the surface of the solution as in the pure solvent. The forces of attraction between solvent-solvent and solute-solute are not same as the between solute - solvent interaction. Thus, both assertion and reason are false.
