Options

  1. APositive deviations from Raoult's law occur when the vapor pressure of a solution is lower than expected based
  2. BPositive deviations from Raoult's law occur when the vapor pressure of a solution is higher than expected base
  3. CPositive deviations from Raoult's law occur when the composition of the solution matches the composition of th
  4. DPositive deviations from Raoult's law occur when the temperature of the solution is higher than expected. Nega

Correct answer

B. Positive deviations from Raoult's law occur when the vapor pressure of a solution is higher than expected base

Step-by-step solution

Correct Option is : (B) Positive deviations from Raoult's law occur when the vapor pressure of a solution is higher than expected based on the ideal behavior of the components. Negative deviations occur when the vapor pressure is lower than expected.
