Writing Equilibrium Constant Expressions
Identify the correct equilibrium constant expression for this equation:
\[
2 \mathrm{NO}(g)+\mathrm{O}_{2}(g) \leftrightarrow 2 \mathrm{NO}_{2}(g)
\]
\( K_{\text {eq }}=\frac{\left[\mathrm{NO}^{2}\left[\mathrm{O}_{2}\right]\right.}{[\mathrm{NO}]^{2}} \)
\( K_{\text {eq }}=\frac{\left[\mathrm{NO}_{2}\right]^{2}}{[\mathrm{NO}]^{2}\left[\mathrm{O}_{2}\right]} \)
\[
K_{\mathrm{eq}}=\frac{[\mathrm{NO}]}{\left[\mathrm{NO}_{2}\right]\left[\mathrm{O}_{2}\right]}
\]
DONE
\( \square \)
