Question

How is vapor pressure affected by the strength of intermolecular attraction in a liquid?

Answer 1

can you provide a definition (preferably in your own words) for what vapour pressure is?

Answer 2

pressure that is exerted by a vapor in equilibrium with a liquid

Answer 3

so if you increase the attraction between molecules at the surface, will more or less molecules tend to enter the gas phase?

Answer 4

less. I think

Answer 5

yeah, less molecules will tend to enter the gas phase (because they're held tighter to one another) as a result less molecules are in the gas phase and the vapour pressure is lower.

Answer 6

Oh ok. Thanks!

Answer 7

no problem !
