The unit of frequency factor in Arrhenius equation is_______________?
Correct answer: A. Same as that of rate constant
- A. Same as that of rate constant
- B. Same as that of activation energy
- C. Dimensionless
- D. None of these
Explanation
In k = A exp(-E/RT), the exponential is dimensionless, so A must carry the same units as k. Those units depend on the reaction order, such as s⁻¹ for a first-order reaction.
