at which temperature will water boil when the external pressure is 30 kPa?

Do you have a graph to read this from? If so that is how you get the answer.
If no graph of vapor pressure vs temperature, then I assume you are to use the Arrhenius equation. Use the following data in that equation.
p1 = 30 kPa
T1 = ?K
P2 = 101.3
T2 = 373 K
