For 10 points, name this process in which molecules stick to a solid surface.
A graph of the rate of catalysis with the strength of this interaction on the x-axis produces a characteristic "volcano curve." The reaction rate is first order in the degree of this process in the EleyRideal mechanism. Shape-selective catalysts are useful for their ability to undergo this process preferentially based on shape or size. That it cannot form more than a (*) single layer is one assumption when deriving an equation for the fractional coverage which quantifies the extent of this process. This process can be physical when caused by van der Waals forces or chemical when caused by covalent bonds. Materials which are good for this process are often porous like silica gel and zeolites because they have a high surface area at small scales.
