Question

Which one of the following is not correct for an ideal solution ?

• A. It must obey Raoult's law
• B. $\Delta H=0$
• C. $\Delta C=0$
• D. $\Delta H=\Delta V\ne 0$

Answer 1

Answer: (D)

The ideal solution must

(i) Obey Raoult's law at all temperatures and pressures

(ii) $\Delta H=0$

(iii) $\Delta V=0$

$\therefore$ (d) statement $\Delta H=\Delta V\ne 0$ is wrong.
