Question

Which mixture does not show positive deviation from raoult's law?

Answer 1

Answer:

hope this helps you

Explanation:

If the vapor pressure of a mixture is lower than expected from Raoult's law, there is said to be a negative deviation. Negative deviations from Raoult's law arise when the forces between the particles in the mixture are stronger than the mean of the forces between the particles in the pure liquids.

Answer 2

Answer:

A mixture of ethanol and water shows positive deviation from Raoult's law. The intermolecular forces present are weaker than those present in the ideal solution. The total vapour pressure of the solution is greater than the total vapour pressure of an ideal solution. Also, the vapour pressure of each component is greater than that predicted from Raoult's law.
