The rate law equation for Ozone reaction
r=k[O][O₂]
<h3>Further explanation</h3>Given
Reaction of Ozone :.
O(g) + O2(g) → O3(g)
Required
the rate law equation
Solution
The rate law is a chemical equation that shows the relationship between reaction rate and the concentration / pressure of the reactants
For reaction
aA + bB ⇒ C + D
The rate law can be formulated:
where
r = reaction rate, M / s
k = constant, mol¹⁻⁽ᵃ⁺ᵇ⁾. L⁽ᵃ⁺ᵇ⁾⁻¹. S⁻¹
a = reaction order to A
b = reaction order to B
[A] = [B] = concentration of substances
So for Ozone reaction, the rate law (first orde for both O and O₂) :
Start by writing the atoms balance:
Now, determine the change of oxidation states:
has oxidation state 0, so each N has to gain 3 electrons to become 
.
That, means that you need 6 electrons to balance the charges, resulting in:
And the answer is 6 mole of electrons.
