" One model of this process states that theta equals K times pressure over 1 plus K times pressure.
The inverse of this process follows Arrhenius-like kinetics according to the PolanyiÂ–Wigner equation. This process occurs indirectly via a "precursor state" according to a kinetic theory of it put forth by Kisliuk. Packed beds used to perform purifications via this process are often operated using a "pressure-swing." One model of this process states that theta equals K times pressure over 1 plus K times pressure. The multi-layer (*) BET model of this process assumes that each layer can be modeled independently by the Langmuir isotherm. Zeolites and silica gel are often used to perform this process due to their high surface areas. This process occurs between hydrogen gas and a metal during catalytic hydrogenation. For 10 points, name this process in which molecules adhere to a solid surface.
The inverse of this process follows Arrhenius-like kinetics according to the PolanyiÂ–Wigner equation.
