Step-by-Step Solution
A mixture of ethanol and acetone shows positive deviation from Raoult's law. In pure ethanol, molecules are held together by strong hydrogen bonding. When acetone is added, it breaks these hydrogen bonds, resulting in weaker solute-solvent interactions, thus increasing vapour pressure.
