According to Raoult's law, what is the relationship between the partial vapor pressure of each component and its mole fraction in the solution?

Options

  1. AThe partial vapor pressure is inversely proportional to the mole fraction.
  2. BThe partial vapor pressure is directly proportional to the mole fraction.
  3. CThe partial vapor pressure is unrelated to the mole fraction.
  4. DThe partial vapor pressure is a constant value for all components.

Correct answer

B. The partial vapor pressure is directly proportional to the mole fraction.

Step-by-step solution

Raoult's law states that for a solution of volatile liquids, the partial vapor pressure of each component of the solution is directly proportional to its mole fraction present in the solution.
