which catalyzed reaction breaks up ozone? 2h2o2(l) mno2 2h2o(l) + o2 o3 + o cl 2o2 2h2o2 (aq) pts 2h2o(l) +…

Explanation:

Step1: Analyze each reaction

We need to find the reaction that involves ozone ($O_3$) being broken - down with a catalyst.

Step2: Check the first reaction

The reaction $2H_2O_2(l)\xrightarrow{MnO_2}2H_2O(l)+O_2$ is the decomposition of hydrogen - peroxide catalyzed by manganese dioxide, not ozone decomposition.

Step3: Check the second reaction

The reaction $O_3 + O\xrightarrow{Cl}2O_2$ shows ozone ($O_3$) reacting with an oxygen atom ($O$) in the presence of chlorine ($Cl$) as a catalyst to form oxygen ($O_2$). This is a well - known ozone - depletion reaction.

Step4: Check the third reaction

The reaction $2H_2O_2(aq)\xrightarrow{Pt_s}2H_2O(l)+O_2$ is the decomposition of hydrogen - peroxide catalyzed by platinum, not ozone decomposition.

Step5: Check the fourth reaction

The reaction $O_2 + 2SO_2\xrightarrow{NO}2SO_3$ is the oxidation of sulfur dioxide to sulfur trioxide catalyzed by nitrogen monoxide, not ozone decomposition.

Answer:

$O_3 + O\xrightarrow{Cl}2O_2$
