Q. Which one of the following is not correct for an ideal solution ?
UPSEE
UPSEE 2005
A
It must obey Raoult's law
B
$ ΔH = 0 $
C
$ ΔC = 0 $
D
$ ΔH = ΔV ≠ 0 $
Solution:
The ideal solution must
(i) Obey Raoult's law at all temperatures and pressures
(ii) $\Delta H=0$
(iii) $\Delta V=0$
$\therefore \quad$ (d) statement $\Delta H=\Delta V \neq 0$ is wrong.
