Question:
The vapor pressure of water in a solution is always _____ the vapor pressure of pure water, when the temperature
of both the solution and solvent are the same with the same external pressure acting over them
The vapor pressure of water in a solution is always _____ the vapor pressure of pure water, when the temperature
of both the solution and solvent are the same with the same external pressure acting over them
Show Hint
The addition of a non-volatile solute to a solvent lowers the vapor pressure, a phenomenon known as Raoult’s law.

- Lower than the vapor pressure of pure water
- Higher than the vapor pressure of pure water
- Equal to the vapor pressure of pure water
- Perpendicular to the vapor pressure of pure water
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The vapor pressure of a solution is always lower than the vapor pressure of pure water due to the presence of solute particles that reduce the number of water molecules at the surface available for evaporation.
