Quizplus · Accepted Answer

The equilibrium expression for the given reaction is $K_c = \frac{[NO]^2}{[N_2O_4]}$. Given $K_c = 0.21$ and $[N_2O_4]_{eq} = 0.033 M$, we can solve for $[NO]$ by rearranging the equation to $[NO] = \sqrt{K_c \times [N_2O_4]}$. Substituting the given values, $[NO] = \sqrt{0.21 \times 0.033} = \sqrt{0.00693}$, which is approximately $0.0832 M$ or $8.3 \times 10^{-2} M$.
