Arrhenius' equation states that:
k = Ae-Ea/RT.
Note that Ea has units of energy and RT also has units of energy, so the exponential is a dimensionless quantity. This means that A has the same units as k. The units of k depend on the particular rate law of the reaction.

Depend on order of reaction (option) is most suitable for this question because frequency factor only exists in 1st order.
