Question: What is the effect of increasing temperature on the vapor pressure of a solvent according to Raoult\'s Law?

Options:

Correct Answer: It increases the vapor pressure.

Solution:

Increasing temperature generally increases the vapor pressure of a solvent, as more molecules have enough energy to escape into the vapor phase.

What is the effect of increasing temperature on the vapor pressure of a solvent according to Raoult's Law?

Step 1: Understand what vapor pressure is. Vapor pressure is the pressure exerted by the vapor of a liquid when it is in equilibrium with its liquid phase.
Step 2: Know that temperature affects the energy of molecules. As temperature increases, the energy of the molecules in the solvent also increases.
Step 3: Realize that higher energy means more molecules can escape. When molecules have enough energy, they can break free from the liquid and enter the vapor phase.
Step 4: Connect this to Raoult's Law. Raoult's Law states that the vapor pressure of a solvent is directly related to its temperature.
Step 5: Conclude that as temperature increases, the vapor pressure of the solvent also increases because more molecules can escape into the vapor.
