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.
