In this question, we have to identify which of the following statements are true.
00:08
So coming to the first statement, the vapor pressure of the solution is directly proportional to the mole fraction of solute.
00:16
So according to roward's law, vapor pressure of the solution is directly proportional to the moles of solute.
00:34
For the lowering of vapor pressure, it becomes directly proportional to the mold fraction of solute.
00:42
But vapor pressure of solution is directly proportional to molds of solute.
00:47
So first statement is false.
00:56
Coming to the next question, when a solute is added to water, the water in the solution has a lower pressure than that of pure ice at 0 degree celsius.
01:15
Ice means solid.
01:19
So solids do not exert any kind of vapor pressure.
01:23
Whereas on adding a solute, the vapor pressure will be lowered, but still, since the solids do not exert any pressure...
