A) there is negative deviation from Raoult's law
B) boiling point is higher than that expected for ideal solution
C) molecular attractions between unlike molecules are stronger than those between like molecules
D) All of these statements are correct
Correct Answer: D
Solution :
[d] For ideal solution vapour pressure of solution \[=P_{A}^{{}^\circ }{{X}_{A}}+P_{B}^{{}^\circ }{{X}_{B}}\] \[=80\times \frac{2}{5}+100\times \frac{3}{5}=92\,torr\] Since observed vapour pressure of solution < ideal vapour pressure, the solution shows negative deviation.You need to login to perform this action.
