As you have seen, ozone is formed in the upper atmosphere through the reaction: O(g) + O2(g) → O3(g)

Data has shown that this is first order with respect to oxygen atoms and first order with respect to diatomic oxygen. Write the rate law equation for this reaction.

The rate law equation for Ozone reaction

r=k[O][O₂]

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) :

what's the

the answer is b. dilution
