Vapor pressure on a liquid

[From: ] [author: ] [Date: 12-06-06] [Hit: ]
Vapor pressure is dependent on the temperature (true for all equilibrium reactions) and the values are tabulated. Try searching on vapor pressure of water for a list of VP values at different temps.......
I'm currently studying for exams and going through old examination papers.
Which of the following is true of the vapor pressure of a liquid?
a. the vapor pressures of all liquids are the same
b. the vapor pressure of a liquid is an equilibrium pressure
c. the vapor pressure of a liquid can be measured in an open container
d. the vapor pressure of a liquid is independent on temperature

I think it's d independent on temp
but i might be wrong, so decided to ask here :)

This is the correct answer:

b. the vapor pressure of a liquid is an equilibrium pressure

Vapor pressure is dependent on the temperature (true for all equilibrium reactions) and the values are tabulated. Try searching on 'vapor pressure of water' for a list of VP values at different temps.
