Adsorption

The adsorption of ensemble molecules on a surface or interface can be devived into two processes adsorption and desorption. If the adsorption rate wins the desorption rate, the molecules will accumulate over time giving the adsorption curve over time. If the desorption rate is larger, the number of molecules on the surface will decrease over time.
