Solution

The correct option is C depends upon order
Arrhenius' equation gives the dependence of the rate constant of a chemical reaction on the absolute temperature, a pre-exponential factor and other constants of the reaction.

$k = A e \frac{- E_{a}}{k_{b} t}$ where A = Frequency factor
The units of the pre-exponential factor A are identical to those of the rate constant and will vary depending on the order of the reaction
