Question

Which of the following statements is true for a solution containing components $A$ and $B$ and following Raoult's law:

• A. $A-B$ attraction force is greater than $A-A$ and $B-B$
• B. $A-B$ attraction force is less than $A-A$ 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 volume of solute and solvent

Answer 1

Answer: (C)

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

Raoult's law is valid for an ideal solution only. The two components $A$ and $B$ follow 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 $B-B$.
