Two liquids A and B have vapour pressure...

Two liquids A and B have vapour pressures 400 mm Hg and 450 mm Hg respectively at a given temperature. Which liquid has higher boiling point?

AI Generated Solution

To determine which liquid has a higher boiling point between liquids A and B, we need to analyze their vapor pressures. ### Step 1: Understand the relationship between vapor pressure and boiling point. The boiling point of a liquid is the temperature at which its vapor pressure equals the atmospheric pressure (usually 760 mm Hg at sea level). A liquid with a higher vapor pressure at a given temperature will boil at a lower temperature compared to a liquid with a lower vapor pressure. ### Step 2: Compare the vapor pressures of liquids A and B. - Liquid A has a vapor pressure of 400 mm Hg. - Liquid B has a vapor pressure of 450 mm Hg. ...
