How is the vapour pressure of a liquid with strong intermolecular attraction generally?
Answer and explanation
Correct answer: Lower
Strong intermolecular attractions hold molecules more firmly within the liquid. At a given temperature, fewer molecules have enough energy to escape into the vapour phase. The equilibrium concentration of vapour is therefore lower, giving a lower vapour pressure and usually lower volatility. Vapour pressure is neither infinite nor negative.
