Question

Explain how each of the following affects the vapour pressure of a liquid:
$b)$ surface area (intermolecular forces )

Answer 1

$b)$
Surface area (an extensive property) has no influence on the vapor pressure, which is again, an intensive property.
However, the intermolecular force strength at the surface would directly influence the surface tension, which varies inversely with the vapor pressure.
Higher intermolecular force strength, higher surface tension and lower vapor pressure.
