Question
![**Reaction Mechanism Explanation:**
Consider the following reaction mechanism. If this mechanism is correct, and \( k_1 \) is much smaller than \( k_2 \), then the observed rate law would be:
1. **Reaction Step 1:**
\[
2A \xrightarrow{k_1} C + I
\]
2. **Reaction Step 2:**
\[
I + B \xrightarrow{k_2} C + D
\]
**Choices for the Observed Rate Law:**
- \( R = k_1 [A]^2 \)
- \( R = k_1 k_2 [A]^2 [I] [B] \)
- \( R = k_1 [A]^2 - k_2 [C] [D] \)
- \( R = k_1 [A] \)
- \( R = k_2 [I] [B] \)
**Explanation:**
The mechanism consists of two steps. In the first step, two molecules of A react to give species C and an intermediate I, with the rate constant \( k_1 \). In the second step, the intermediate I reacts with B to produce species C and D, with the rate constant \( k_2 \).
Since \( k_1 \) is much smaller than \( k_2 \), the first step is likely the rate-determining step. The observed rate law will depend on the concentration of reactants involved in this slowest step.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fddfa7f77-4569-4dbd-92cb-fd284a2ed2ea%2Fe6b7a490-603d-4202-ab2d-f7efbd3161d5%2F8s61ar.png&w=3840&q=75)
