What is the overall order of the reaction and the order with respect to [O3]?

Consider the reaction

2O3(g)    ->    3O2(g)

rate =  k[O3]^2 [O2]^−1 .
What is the overall order of the reaction and the order with respect to [O3]?

there are answer choices:
1. −1 and 3
2. 0 and 1
3. 1 and 2
4. 3 and 2
5. 2 and 2

Please explain how to do it too, I need to know how to work it out.

When you are given a rate equation, let say

rate = k [A]^x [B]^y [C]^z

we can say that the order of reaction with respect to (wrt) A is x.
The order of reaction wrt B is y and
the order of reaction wrt C is z.

The overall order of reaction is x + y + z

So, the answer to your question is obvious.
It is 3) 1 and 2

overall order is 2 + (-1) = 1
