Ostwald–Freundlich equation

The Ostwald–Freundlich equation governs boundaries between two phases; specifically, it relates the surface tension of the boundary to its curvature, the ambient temperature, and the vapor pressure or chemical potential in the two phases.

The Ostwald–Freundlich equation for a droplet or particle with radius ${\displaystyle R}$ is:

${\displaystyle {\frac {p}{p_{eq}}}=\exp {\left({\frac {R_{critical}}{R}}\right)}}$

${\displaystyle R_{critical}={\frac {2\cdot \gamma \cdot V_{Atom}}{k_{B}\cdot T}}}$
