Question

A solution containing components A and B follows 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

Correct option (c) A - B attraction force remains same as A - A and B - B

Explanation :

Raoult's law is valid for ideal solution only. The element of non-ideality enters into the picture when the molecules of the solute and solvent affect each others intermolecular forces. A solution containing components of A and B behaves as ideal solution when A - B attraction force remains same as A - A and B - B.
