Question

What type of deviation is shown by a mixture of ethanol and acetone give reason?

Answer 1

Hey !!

It shows positive deviation

It is due to weaker interactions between acetone and ethanol-ethanol interactions.

GOOD LUCK !!

Answer 2

Hey Dear,

● Answer -

Mixture of ethanol and acetone shows positive deviation from Raoult's law.

● Reason -

• Positive deviation occurs when the vapour pressure of the component is greater than what is expected in Raoult's Law.
• In mixture of ethanol & acetone, cohesive forces are more stronger than adhesive forces of attraction.
• Thus, vapor pressure of mixture is always greater than what is expected from ideal solution.
• Thus, mixture of ethanol and acetone shows positive deviation.

Thanks for asking..
