# Vapor Pressure and Container

The following comes from my text and concerns vapor pressure: Consider a liquid in a closed, cylindrical container that is half full. The molecules at the surface of the container and along the edges have the fewest neighbors; therefore, they will evaporate more quickly than other molecules. This intuitively makes sense.

The text also says that vapor pressure is independent of the shape and volume of a container. Now consider the above situation in two cylinders of the same volume. The first has a much smaller radius than the second. Since the smaller radius cylinder has a greater proportion of its molecules along the edges, I would think that it would have a slightly higher vapor pressure. Is this correct? Perhaps I'm just over-complicating things. Any help is appreciated!
