Q. Assertion A: For an ideal solution formed by mixing liquids P and Q, ΔmixH = 0 and ΔmixV = 0 Reason R: No interactions occur between P and Q In the light of the above statements, choose the most appropriate answer from the options given below.
A) A is not correct but R is correct
B) Both A and R are correct and R is the correct explanation of A
C) Both A and R are correct but R is NOT the correct explanation of A
D) A is correct but R is not correct
Explanation
[Solution from source] For an ideal solution there is no heat or volume change on mixing, so A is true. R is false: P–Q interactions exist, but are of the same strength as the P–P and Q–Q interactions they replace. Answer (4).
