All right.
00:01
We have four statements here.
00:01
We want to identify what's true, what's false, and correct the false.
00:05
So is vapor pressure directly related to the moll fraction of the solute? well, we know that the vapor pressure is going to be the pressure of the pure substance times typically written the mulfraction of the solvent.
00:33
So this is one minus the mole fraction of the solute.
00:52
So then let's see, it's directly proportional to the solvent one.
01:05
So as the solvent concentration goes up, so does the vapor pressure.
01:09
As the solute concentration goes up, that means it goes down.
01:12
So it's inversely proportional.
01:20
Inversely.
01:22
So as written, this is going to be false.
01:25
All right.
01:25
Then we have, if you add a solute, the water has a lower vapor pressure than pure ice.
01:33
And that's true because vapor pressure lowering when you know.
01:35
Add solutes, the vapor pressure becomes lower...
