Question

The BET (“B-E-T”) and Langmuir (“LANG-myoor”) isotherms model this process. For 10 points each:
[10e] Name this process in which gas or liquid molecules bind to the surface of a material.
ANSWER: adsorption (“ad-ZORP-shin”) [or adsorbing; reject “absorption”]
[10h] The BET isotherm expands on the Langmuir isotherm by modeling adsorptions in systems with this property. Two different enthalpies of adsorption are assigned by the BET isotherm to model systems with this property.
ANSWER: multilayers [or multiple layers; accept adsorbing onto existing adsorbents]
[10m] In the Langmuir isotherm, the fractional occupancy can be found by multiplying an equilibrium constant by this quantity and then dividing by that same expression plus 1. The mole fraction of a solution is proportional to this quantity for the gas.
ANSWER: partial pressure [prompt on pressure]
