![**Question 2**
The decomposition of hydrogen peroxide is catalyzed by iodide in a two-step process:
1. \( \text{H}_2\text{O}_2 + \text{I}^- \rightarrow \text{H}_2\text{O} + \text{IO}^- \) (slow)
2. \( \text{IO}^- + \text{H}_2\text{O}_2 \rightarrow \text{H}_2\text{O} + \text{O}_2 + \text{I}^- \) (fast)
Overall reaction:
\[
\underline{2\text{H}_2\text{O}_2 \rightarrow 2\text{H}_2\text{O} + \text{O}_2}
\]
**What is the rate law predicted by this mechanism?**
- ○ Rate = k[\(\text{H}_2\text{O}_2\)]
- ○ Rate = k[\(\text{H}_2\text{O}_2\)][\(\text{I}^-\)]
- ○ Rate = k[\(\text{H}_2\text{O}_2\)]^2
- ○ Rate = k[\(\text{H}_2\text{O}_2\)][\(\text{IO}^-\)]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F824fa1c6-40a3-49c1-bdd2-6faa45715099%2F25951091-41d3-4a07-97a2-545d0d144f9b%2Fisja8lp_processed.jpeg&w=3840&q=75)

Expert Solution

Step 1
Rate of reaction depends on slow step reaction, because it is a rate determining step.
H2O2 + I ➡️ H2O + IO-
So rate of reaction depends on concentration of reactants of slow step reaction.
