The normal boiling points of ethanol and...

The normal boiling points of ethanol and benzene are `78.3^(@)C` and `80^(@)C`, respectively. Is the vapour presure of ethanol lower than, greater than or equal to the vapour pressure of benzene?

Text Solution

Verified by Experts

At the normal boiling point of a liquid, the vapour pressure of the liquid is equal to the atmospheric pressure. Therefore, the vapour pressure of ethanol at `78.3^(@)C` and that of benzene at `80^(@)C` are the same and equal to 1 atm.
