A sample of ethanoic acid is at 85°C. At a pressure of 50 kPa, what increase in temperature is needed to reach the boiling point of ethanoic acid?

We don't know.

Explanation:

The normal boiling point of ethanoic acid is #118-119# #""^@C#. This is a physical property of acetic acid, which you probably would not know offhand. So at #118-119# #""^@C#, the vapour pressure of acetic acid is #1# #atm#.

At #50# #kPa#, a reduced pressure, the boiling point of acetic acid is unknown, and is the subject of experiment, which we ain't got. Of course it would be less than #118-119# #""^@C#, but we need more data.
