How is the vapour pressure of a more volatile liquid?
Answer and explanation
Correct answer: Higher
Volatility describes how readily a liquid changes into vapour. In a more volatile liquid, intermolecular attractions are comparatively easier to overcome, so more molecules escape from the surface at the same temperature. At equilibrium this produces a higher vapour pressure. Vapour pressure cannot be negative or necessarily zero.
