Destroyer Rate Law Problem- Gen Chem

[Liz Cecilia]

In the gen chem section of my destroyer (#23 in the 2012 section), there is a long-ish reaction written out, and you're supposed to write out the rate law. In the answer section though, it says that the "correct rate law" can only be determined though experimentation. Therefore, none of the answer choices are possible.

Is that right? I could have sworn that it would just be the (slow step in bimolecular) reactants in "[ ]" multiplied by each other.

You can determine rate law through A)Mechanisms, aka elementary steps, with rate determining step given. B)experimental data. The problem offers none of the above, therefore it is impossible to determine the actual rate law.
