Question

A cylinder fitted with a movable piston contains liquid water in equilibrium with water vapour at 25°C. Which of the following operation(s) results in a decrease in the equilibrium vapour pressure at 25°C?

Prashant Kotian · Accepted Answer

Correct answer: D. Vapour pressure of a pure liquid depends only on temperature. Only dissolving a non-volatile salt (d) lowers equilibrium vapour pressure by Raoult's law.
