Why is the vapor pressure of an aqueous solution of glucose lower than that of water?
Options
- AGlucose molecules are more volatile than water molecules.
- BGlucose molecules occupy positions on the liquid surface, reducing water's surface coverage.
- CGlucose molecules increase the kinetic energy of water molecules, lowering vapor pressure.
- DGlucose molecules react with water, reducing the vapor pressure.
Correct answer
B. Glucose molecules occupy positions on the liquid surface, reducing water's surface coverage.
Step-by-step solution
Correct Option is : (B) Glucose molecules occupy positions on the liquid surface, reducing water's surface coverage.
