Which of the following is not a unit of reaction rate ?
Correct answer: D. None of these
- A. Moles for med/(surface of catalyst) (time)
- B. Moles formed/volume of reactor) (time)
- C. Mole formed/volume of catalyst) (time)
- D. None of these
Explanation
Reaction rate may be expressed per reactor volume, catalyst volume, or catalyst surface area, provided the basis is stated. Therefore, all of options a, b, and c are valid rate units, making 'none of these' correct.
