One of the oxygen atoms in the anion O3− is hypervalent and the formal charge on this oxygen atom is -1.
Ozone is a triatomic molecule. The anion formed from ozone is called the ozonide anion. This anion is also triatomic. The resonance structures of the ozonide anion are shown in the image attached to this answer.
We can see that one of the oxygen atoms in the ozonide ion is hypervalent because it contains ten instead of eight electrons. This hypervalent oxygen atom has a formal charge of -1 while the two other oxygen atoms has a formal charge of zero.

Answer:
(a). second order.
(b). zeroth order.
(c). one and a half order.
(d). third order.
Explanation:
Hello,
In this case, you just have to add the concentration's powers in each rate law:
(a)
Just the 2-power is present, so it is a second order law.
(b)
No power is present, so it is a zeroth order law.
(c)
1 plus 1/2 gives 1.5, that is why it is a 1.5 (one and a half) order law.
(d)
2 plus 1 gives 3, that is why it is a third order law.
Best regards.
