Question
**Chemical Kinetics Problem: Decomposition of Dinitrogen Pentoxide (N₂O₅)**

Consider the reaction:
\[ 2N_2O_5 (g) \rightarrow 2N_2O_4 (g) + O_2 (g) \]

At a certain temperature, it obeys the following rate law:

\[ \text{rate} = (0.0317 \ M^{-1} \ s^{-1}) [N_2O_5]^2 \]

**Problem Statement:**
Suppose a vessel contains \( N_2O_5 \) at a concentration of \( 0.440 \ M \). Calculate the concentration of \( N_2O_5 \) in the vessel \( 480 \) seconds later. Assume no other reaction is important.

**Instructions:**
- Round your answer to 2 significant digits.

**Input Field:**
Concentration after 480 seconds: ___________ M

Submit button options:
\[ \text{[x]} \quad \text{[⟲]} \quad \text{[?]} \]

---

**Explanation:**
The input field allows the user to enter the calculated concentration. The buttons likely serve the following functions:
- **[x]**: Submit or confirm the entered value
- **[⟲]**: Reset or clear the entered value
- **[?]**: Access hints or help related to the problem
