Langmuir isotherm
Surface coverage equation
The Langmuir isotherm is a model describing how molecules adsorb onto a surface, assuming a fixed number of identical sites where only a single layer of molecules can attach.
At low concentrations, adsorption increases proportionally; at high concentrations, the surface saturates and levels off.
The model is foundational in surface chemistry and catalysis: The data fit a Langmuir isotherm, suggesting monolayer coverage.
