adsorption thermodynamics

Adsorption thermodynamics describes how molecules stick to a surface, like ink on paper or gases on a solid. It involves energy changes: when molecules attach to the surface, energy is released or absorbed, depending on conditions like temperature and pressure. This process reaches equilibrium where the rate of molecules sticking equals those leaving. Key factors include the affinity between molecules and the surface, as well as temperature, which influences how much molecules prefer to stay attached. Understanding these energy changes helps in designing processes like catalysis, filtration, and sensor development.
