Which of the following holds good for a solution obeying Raoult's law (i.e., an ideal solution) (where, ΔH = heat of mixing, and ΔV = volume change on mixing) ?
Correct answer: D. Both B. and C.
- A. ΔH = 1 (+ ve) and Δ V = -ve
- B. ΔH = 0
- C. ΔV = 0
- D. Both B. and C.
Explanation
An ideal solution has zero enthalpy and zero volume change on mixing because intermolecular interactions are effectively unchanged. Therefore both ΔH = 0 and ΔV = 0 apply.
