Q. Which one of the following is incorrect for ideal solution?
A) $\Delta H_{mix} = 0$
B) $\Delta U_{mix} = 0$
C) $\Delta P = P_{obs} - P_{calculated\ by\ Raoult's\ law} = 0$
D) $\Delta G_{mix} = 0$
Explanation
[Solution] Mixing to form an ideal solution is spontaneous, so $\Delta G_{mix} < 0$. Answer (4).
