Question: Which of the following is a consequence of Raoult\'s Law in a binary solution?

Options:

The total vapor pressure is the sum of the partial pressures.
The total vapor pressure is always lower than the vapor pressure of the pure solvent.
The mole fraction of the solute is always greater than that of the solvent.
The boiling point of the solution is always higher than that of the pure solvent.

Correct Answer: The total vapor pressure is the sum of the partial pressures.

Solution:

According to Raoult\'s Law, the total vapor pressure of a binary solution is the sum of the partial pressures of each component.

Which of the following is a consequence of Raoult's Law in a binary solution?

Correct Answer: Total vapor pressure is the sum of partial pressures.

Step 1: Understand that a binary solution consists of two components (let's call them A and B).
Step 2: Know that Raoult's Law states that the vapor pressure of each component in the solution is proportional to its mole fraction in the solution.
Step 3: Identify the partial vapor pressure of component A (P_A) and component B (P_B).
Step 4: Calculate the total vapor pressure (P_total) of the solution by adding the partial pressures: P_total = P_A + P_B.
Step 5: Remember that the total vapor pressure is influenced by the amount of each component present in the solution.
