Which of the following is not a unit of reaction rate ?
Correct answer: C. None of these
- A. Moles for med/(surface of catalyst) (time)
- B. Moles formed/volume of reactor) (time)
- C. None of these
- D. Mole formed/volume of catalyst) (time)
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.
