How Does the Radius of Curvature Affect Vapor Pressure?
The radius of curvature (r) plays a critical role in determining vapor pressure. A smaller radius (i.e., a more curved surface) leads to a higher vapor pressure, as described by the Kelvin Equation. This is particularly relevant for nanoparticles and nanopores, where curvature effects are pronounced. For example, in a nanoporous material, the small pores can significantly elevate the vapor pressure, affecting adsorption and desorption processes.
