An algorithm used to model this process developed by members of WUSTL’s Gelb lab incorporates tetrominoes as proxies for molecules. Chemical species must first enter a “precursor state” before participating in this process, according to a theory developed by Paul Kisliuk. The enthalpy of this process is plotted against reaction rate in a volcano plot. One form of this process, which is dependent on the vapor pressure of the participating molecules, is studied in (*) BET (“B-E-T”) theory. The Langmuir isotherm is another model used to examine this process, which concerns the formation of monolayers. Due to their high surface areas, (-5[1])porous materials (10[1])such as zeolites and activated charcoal are effective at conducting (-5[1])this process. For 10 points, name this process in which molecules adhere to a solid surface. ■END■ (10[3])
