**Translation of the Question:**

The given chemical reaction is:
\[ 2NO_2(g) \rightarrow 2NO(g) + O_2(g) \]

Based on the time vs. moles graph:

**a)** Calculate the average rate of reaction for the production of \( NO_2 \) between 2 and 6 minutes in units of \( \text{mol}/L \cdot \text{min} \).

**b)** Determine the time period during which the reaction rate is higher.

---

### Explanation of the Problem:

1. **Part a)** asks for the calculation of the average rate of reaction. To do this, you would use the following formula:
   \[
   \text{Rate} = \frac{\Delta [\text{Reactant or Product}]}{\Delta t}
   \]
   Where:
   - \( \Delta [\text{Reactant or Product}] \) is the change in concentration of the substance over the given time interval.
   - \( \Delta t \) is the change in time (6 - 2 minutes in this case).

2. **Part b)** asks about identifying the time period where the reaction rate is higher, based on the graph.
