BET apparatus is used to determine the ___________________?
Correct answer: D. Specific surface of a porous catalyst
- A. Porosity of the catalyst bed
- B. Pore size distribution
- C. Pore diameter
- D. Specific surface of a porous catalyst
Explanation
BET adsorption analysis measures the specific surface area by determining the amount of gas required to form a monolayer on the solid. Pore-size distribution and porosity require additional analysis or interpretation beyond the primary BET measurement.
