pressure to condense

(1/2) > >>

Ice-cream:
can any1 give me some help on this question:

What pressure would have to be applied to steam at 300 degrees C to condense it into liquid water (delta H(vap) = 40.7 kJ/mol)?

Ans. 97.6 atm

I really have no idea wat to do, i can't even start it!! i don't even know which formulae would be used...any1 got any ideas?

Grafter:
You need to take the clasius clapyron equation, and take it from there.
use the fact that at boiling point, the pressure of the vapor is 1 atmosphere.

ksr985:
If i remember correctly, i answered one of your earlier questions using the clausius clapeyron eqn. Very similar question.

Grafter:
Just looked back - yes, very similar question.

Ice-cream:
