A) Behaves like a near ideal solution
B) Obeys Raoulfs law
C) Shows a negative deviation from Raoult's law
D) Shows a positive deviation from Raoult's law
Correct Answer: D
Solution :
Shows a positive deviation from Raoulfs law Acetone ethanol, it is non-ideal solution i.e. does not by Raoult's law. It shows positive derivation. \[\Rightarrow {{P}_{A}}>{{X}_{A}}P{{{}^\circ }_{\operatorname{A}}},{{P}_{B}}>{{X}_{B}}P{}^\circ \] PfotxA+Xb \[{{P}_{\operatorname{total}}}>{{X}_{A}}P{}^\circ A+{{X}_{B}}P{}^\circ B\] \[\Rightarrow \Delta {{\operatorname{H}}_{mixing}}=+ve\]You need to login to perform this action.
