The decomposition of nitrogen dioxide is described by the following chemical equation:
2NO_2 (g) --------> 2NO (g) + O_2 (g)
Suppose a two-step mechanism is proposed for this reaction, beginning with this elementary reaction:
NO_2 (g) --------> NO_(g) + O_(g)
Suppose also that the second step of the mechanism should be bimolecular.
a) Suggest a reasonable second step. That is, write the balanced chemical equation of a bimolecular elementary reaction that would complete the proposed mechanism.

Answer:

The balanced chemical equation will be "[tex]NO_{2}+O\rightarrow NO+O_{2}[/tex]".

Explanation:

The given equation is:

[tex]2NO_{2}\rightarrow 2NO+O_{2}[/tex]

Step 1:

[tex]2NO_{2}\rightarrow NO+O[/tex]...(equation 1)

Step 2:

[tex]NO_{2}+O\rightarrow NO+O_{2}[/tex]...(equation 2)

On adding "equation 1" and "equation 2", we get

⇒  [tex]NO_{2}+NO_{2}+O\rightarrow NO+O+NO+O_{2}[/tex]

⇒  [tex]2NO_{2}\rightarrow 2NO+O_{2}[/tex]

The second step:

⇒  [tex]NO_{2}+O\rightarrow NO+O_{2}[/tex]
