# The decomposition of ozone, \(\text{O}_3\text{(g)}\), is proposed to occur through the following two-step mechanism:

Step 1: \(\text{O}_3\text{(g)} \rightleftharpoons \text{O}_2\text{(g)} + \text{O(g)}\)
Step 2: \(\text{O}_3\text{(g)} + \text{O(g)} \rightarrow 2\,\text{O}_2\text{(g)}\)

Which of the following represents the overall balanced chemical equation for the reaction?

The decomposition of ozone, \(\text{O}_3\text{(g)}\), is proposed to occur through the following two-step mechanism:

Step 1: \(\text{O}_3\text{(g)} \rightleftharpoons \text{O}_2\text{(g)} + \text{O(g)}\)
Step 2: \(\text{O}_3\text{(g)} + \text{O(g)} \rightarrow 2\,\text{O}_2\text{(g)}\)

Which of the following represents the overall balanced chemical equation for the reaction?

- **A.** \(2\,\text{O}_3\text{(g)} \rightarrow 3\,\text{O}_2\text{(g)}\)
- **B.** \(2\,\text{O}_3\text{(g)} + \text{O(g)} \rightarrow 3\,\text{O}_2\text{(g)} + \text{O(g)}\)
- **C.** \(\text{O}_3\text{(g)} + \text{O(g)} \rightarrow 2\,\text{O}_2\text{(g)}\)
- **D.** \(\text{O}_3\text{(g)} \rightarrow \text{O}_2\text{(g)} + \text{O(g)}\)
