Suppose the formation of dinitrogen pentoxide proceeds by the following mechanism: step elementary reaction rate constant 1 NO₂(g) + O2(g) → NO3(g) + O₂(g) k₁ 2 NO3(9) + NO2(g) → N₂O5(g) k₂ Suppose also k₁«k₂. That is, the first step is much slower than the second. Write the balanced chemical equation for the 0 overall chemical reaction: Write the experimentally- observable rate law for the overall chemical reaction. Note: your answer should not contain the concentrations of any intermediates. Express the rate constant k for the overall chemical reaction in terms of K₁, K2, and (if necessary) the rate constants k-1 and k-2 for the reverse of the two elementary reactions in the mechanism. rate = k k = 0

![**Formation of Dinitrogen Pentoxide Study**
Suppose the formation of dinitrogen pentoxide proceeds by the following mechanism:
| Step | Elementary Reaction | Rate Constant |
|---|---|---|
| 1 | NO₂(g) + O₃(g) → NO₃(g) + O₂(g) | k₁ |
| 2 | NO₃(g) + NO₂(g) → N₂O₅(g) | k₂ |
Suppose also \( k_1 < k_2 \). That is, the first step is much slower than the second.
1. **Write the balanced chemical equation for the overall chemical reaction:**
[Balanced Chemical Equation]
2. **Write the experimentally-observable rate law for the overall chemical reaction.**
*Note: Your answer should not contain the concentrations of any intermediates.*
\[
\text{rate} = k \cdot [\text{Rate Law Expression}]
\]
3. **Express the rate constant \( k \) for the overall chemical reaction in terms of \( k_1 \), \( k_2 \), and (if necessary) the rate constants \( k_{-1} \) and \( k_{-2} \) for the reverse of the two elementary reactions in the mechanism.**
