# At a constant temperature \(T\), the equilibrium constants for the following reactions are given:

\[
\begin{aligned}
2\,\text{NO}_2\text{(g)} &\rightleftharpoons 2\,\text{NO(g)} + \text{O}_2\text{(g)} \quad &K_1 = 4.0 \times 10^{-4} \\
\text{N}_2\text{O(g)} + \text{NO}_2\text{(g)} &\rightleftharpoons 3\,\text{NO(g)} \quad &K_2 = 6.0 \times 10^{-2}
\end{aligned}
\]

Based on this information, what is the value of the equilibrium constant, \(K_c\), for the reaction represented below at the same temperature?

\[
2\,\text{N}_2\text{O(g)} + \text{O}_2\text{(g)} \rightleftharpoons 4\,\text{NO(g)}
\]

At a constant temperature \(T\), the equilibrium constants for the following reactions are given:

\[
\begin{aligned}
2\,\text{NO}_2\text{(g)} &\rightleftharpoons 2\,\text{NO(g)} + \text{O}_2\text{(g)} \quad &K_1 = 4.0 \times 10^{-4} \\
\text{N}_2\text{O(g)} + \text{NO}_2\text{(g)} &\rightleftharpoons 3\,\text{NO(g)} \quad &K_2 = 6.0 \times 10^{-2}
\end{aligned}
\]

Based on this information, what is the value of the equilibrium constant, \(K_c\), for the reaction represented below at the same temperature?

\[
2\,\text{N}_2\text{O(g)} + \text{O}_2\text{(g)} \rightleftharpoons 4\,\text{NO(g)}
\]

- **A.** \(1.4 \times 10^{-6}\)
- **B.** \(2.4 \times 10^{-5}\)
- **C.** \(1.1 \times 10^{-1}\)
- **D.** \(9.0\)
