![### Reaction Problem on Ozone Layer
**Problem 6:** *(Show your work)* Some damage to the ozone layer of the upper atmosphere might involve the reaction:
\[
\text{NO} + \text{O}_3 \leftrightarrow \text{NO}_2 + \text{O}_2
\]
The reaction is first order in **each reactant** and the rate constant (k) is equal to \(1.3 \times 10^6 \, \text{L/(mol s)}\) at 298 K. If the initial concentrations of \(\text{NO}\) and \(\text{O}_3\) are both equal to \(1.00 \times 10^{-6} \, \text{mol/L}\), find the concentrations of \(\text{NO}\) at \(t = 2.00 \, \text{s}\).
---
**Solution Methodology:**
1. **Understanding the Reaction:**
- The reaction involves nitric oxide (\(\text{NO}\)) and ozone (\(\text{O}_3\)) forming nitrogen dioxide (\(\text{NO}_2\)) and oxygen (\(\text{O}_2\)).
- It is first order with respect to each reactant, hence the rate law is:
\[
\text{Rate} = k[\text{NO}][\text{O}_3]
\]
2. **Using Integrated Rate Laws:**
- For a reaction where both reactants are of first order, use integrated rate laws to determine concentration over time:
\[
\text{ln} \left(\frac{[\text{A}]}{[\text{A}]_0}\right) = -kt
\]
- However, this equation needs to be adjusted to account for both reactants, typically using logarithmic adjustments for first order interdependence.
3. **Calculations:**
- Determine the concentration of \([\text{NO}]\) at \(t = 2.00 \, \text{s}\).
- Given initial concentrations and the rate constant, calculations involve solving for the change in concentration over specified time using the appropriate logarithmic relations.
This is a typical kinetic problem analyzing the degradation of ozone, critical for understanding environmental chemistry impacts, particularly in atmospheric studies.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff0d5df92-669c-458d-98aa-d7a992a03f49%2F9d5ed91d-c76c-468c-9ead-30346b5f5bca%2Fvzo1y69_processed.png&w=3840&q=75)
