Which of the following is not a chemical step in a fluid solid catalytic reaction ?
Correct answer: D. None of these
- A. Surface chemical reaction
- B. Adsorption
- C. Desorption
- D. None of these
Explanation
Adsorption, surface reaction, and desorption are all chemical steps in the usual mechanism for a fluid-solid catalytic reaction. Therefore, none of the listed processes is excluded.
