# why vapour pressure doesnt depend upon surface area?

vapur pressure does not depend on surface area because when surface area increases, the number vapours produced from the surface also increases (as due to large area). Hence, the ratio of no: of vapours produced, to surface area remains the same, and vapour pressure remains independent of the surface area.

also, vapour pressure is an intensive property, so it will be independent of size and shape of the vessel.
