Which of the following factors does NOT affect the vapor pressure of a solution according to Raoult's Law?
Nature of the solute
Temperature
Mole fraction of the solvent
Pressure of the system
Raoult's Law states that the vapor pressure is affected by the nature of the solute, temperature, and mole fraction of the solvent, but not by the pressure of the system.

Q: Which of the following factors does NOT affect the vapor pressure of a solution according to Raoult's Law?
Solution: Raoult's Law states that the vapor pressure is affected by the nature of the solute, temperature, and mole fraction of the solvent, but not by the pressure of the system.
Steps: 5
Step 1: Understand what vapor pressure is. It is the pressure exerted by a vapor in equilibrium with its liquid or solid phase.
Step 2: Learn about Raoult's Law. It states that the vapor pressure of a solution depends on the nature of the solute, the temperature, and the mole fraction of the solvent.
Step 3: Identify the factors that affect vapor pressure according to Raoult's Law: solute type, temperature, and solvent amount (mole fraction).
Step 4: Recognize that the pressure of the system itself does not affect the vapor pressure of the solution according to Raoult's Law.
Step 5: Conclude that the factor that does NOT affect vapor pressure is the pressure of the system.
