A. [tex]2 H_2 O_2(l) \xrightarrow{\text{Lus}} O_2 + 2 H_2 O(l)[/tex]
B. [tex]O_3 + O \xrightarrow{a} 2 O_2[/tex]
C. [tex]2 H_2 O_2(aq) \xrightarrow{\text{B Zt}_3} 2 H_2 O(l) + O_2[/tex]
D. [tex]O_2 + 2 SO_2 \xrightarrow{\text{NO}} 2 SO_3[/tex]



Answer :

To determine which catalyzed reaction breaks up ozone, let's examine the given reactions.

1. [tex]\( 2 \text{H}_2\text{O}_2 (l) \xrightarrow{\text{Lus}} 2 \text{H}_2\text{O}(l) + \text{O}_2 \)[/tex]

- This reaction involves the decomposition of hydrogen peroxide into water and oxygen. Ozone is not involved in this reaction.

2. [tex]\( \text{O}_3 + \text{O} \xrightarrow{a} 2 \text{O}_2 \)[/tex]

- In this reaction, ozone ([tex]\( \text{O}_3 \)[/tex]) reacts with an oxygen atom ([tex]\( \text{O} \)[/tex]) to form two molecules of oxygen ([tex]\( \text{O}_2 \)[/tex]). This reaction directly involves the breakdown of ozone.

3. [tex]\( 2 \text{H}_2\text{O}_2 (aq) \xrightarrow{\text{BZt}_3} 2 \text{H}_2\text{O}(l) + \text{O}_2 \)[/tex]

- Similar to the first reaction, this reaction involves the decomposition of hydrogen peroxide in aqueous form, resulting in water and oxygen. Again, ozone is not involved in this reaction.

4. [tex]\( \text{O}_2 + 2 \text{SO}_2 \xrightarrow{\text{NO}} 2 \text{SO}_3 \)[/tex]

- This reaction involves the oxidation of sulfur dioxide ([tex]\( \text{SO}_2 \)[/tex]) to sulfur trioxide ([tex]\( \text{SO}_3 \)[/tex]) using oxygen ([tex]\( \text{O}_2 \)[/tex]). Ozone is not involved in this reaction either.

Among the given reactions, the second reaction clearly describes the breakup of ozone ([tex]\( \text{O}_3 \)[/tex]) to form oxygen molecules ([tex]\( \text{O}_2 \)[/tex]).

Thus, the reaction that breaks up ozone is:
[tex]\[ \text{O}_3 + \text{O} \xrightarrow{a} 2 \text{O}_2 \][/tex]

This corresponds to option 2.
