Brunauer, Emmet and Teller (BET) equation is used to determine the specific surface area of a porous particle but not the pore volume & the porosity of the catalyst bed. Which of the following postulates is not used to derive BET equation?
AThe adsorbed layer may be polymolecular in thickness and the heat of adsorption in each layer
BThere is no dynamic equilibrium between successive layer
CLangmuir’s assumption applies to every adsorbed layer
DNone of these
Correct answer
B. There is no dynamic equilibrium between successive layer
Explanation
The correct answer is There is no dynamic equilibrium between successive layer.
