It decreases the vapor pressure.
It increases the vapor pressure.
It has no effect.

Q: What is the effect of increasing temperature on the vapor pressure of a solution?
Solution: Increasing temperature generally increases the vapor pressure of a solution due to increased kinetic energy of the molecules.
Steps: 5
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. When temperature increases, the molecules in the solution gain more kinetic energy.
Step 3: Realize that with more kinetic energy, more molecules can escape from the liquid phase into the vapor phase.
Step 4: Conclude that as more molecules escape into the vapor phase, the vapor pressure increases.
Step 5: Summarize that increasing temperature leads to an increase in vapor pressure because of the increased movement and energy of the molecules.
