Acetone + ethanol is an example of solutions showing positive deviation from Raoult's law. Since acetone-ethanol attractions are weaker than acetone - acetone and ethanol-ethanol attractions.

Which of the following solutions shows positive deviation from Raoults...
Acetone + Ethanol
Acetone and ethanol form a solution that shows positive deviation from Raoult's law. This means that the vapor pressure of the solution is higher than what would be expected based on Raoult's law.
Reason for Positive Deviation:
- Acetone and ethanol molecules have different molecular sizes and polarities. When mixed together, they do not interact as strongly with each other as they do with their own molecules. This results in weaker intermolecular forces between the acetone and ethanol molecules in the solution.
- Due to the weaker interactions between the molecules, the escaping tendency of the molecules from the solution increases. This leads to a higher vapor pressure compared to what would be predicted by Raoult's law.
Consequence of Positive Deviation:
- Positive deviation from Raoult's law results in a solution that has a higher vapor pressure than expected. This means that the solution boils at a lower temperature and has a higher volatility than predicted by Raoult's law.
- The composition of the vapor phase is different from that of the liquid phase in a positively deviating solution. This can have implications in various industrial processes where accurate knowledge of vapor-liquid equilibrium is required.
In conclusion, the acetone + ethanol solution exhibits positive deviation from Raoult's law due to the differences in molecular interactions between the two components. This deviation leads to higher vapor pressure and different vapor-liquid equilibrium behavior compared to ideal solutions.
