What does it mean when a solution exhibits a positive deviation from Raoult's law?

Options

  1. AThe solution has a higher vapor pressure than predicted by Raoult's law.
  2. BThe solution has a lower vapor pressure than predicted by Raoult's law.
  3. CThe solution has zero vapor pressure.
  4. DThe solution obeys Raoult's law accurately.

Correct answer

A. The solution has a higher vapor pressure than predicted by Raoult's law.

Step-by-step solution

A positive deviation means that the solution has a higher vapor pressure than predicted by Raoult's law.
