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 ?

Question

Accepted Answer

There is no dynamic equilibrium between successive layer. The BET equation assumes that there is a dynamic equilibrium between successive adsorbed layers. Therefore, the statement 'There is no dynamic equilibrium' is not used in its derivation.
