A solution containing components A and B follows Raoult's law, when

A

A - B attraction force is greater than A - A and B - B

B

A - B attraction force remains same as A - A and B - B

C

A - B attraction force remains same as A - A and B - B

D

volume of solution is different from sum of volumes of solute and solvent

Text Solution

Verified by Experts

The correct Answer is:
C
Raoult's law is valid for ideal solution only. These two components A andB follows the condition of Raoult's law, if the force of attraction between A and B is equal to the force of attraction between A-A and B-B.
