#73 on rate laws.

After determining that the rate order for was 0, why does it say in the last sentences that it is 3? I understand why [A] is 2, but why is order of 3 when the solutions calculated it to be 0?
Thanks

That is if the rate law was 5th order reaction, which in that case would have to be 3. The last sentence is just giving another example and not actually the answer to question # 73. Hope that helps.
