The decomposition of $N_2O_4$ to $NO_2$ is carried out at $280 \ K$ in chloroform. When equilibrium has been established,$0.2 \ mol$ of $N_2O_4$ and $2 \times 10^{-3} \ mol$ of $NO_2$ are present in $2 \ L$ solution. The equilibrium constant for the reaction $N_2O_4 \rightleftharpoons 2NO_2$ is:
- A$1 \times 10^{-2}$
- B$2 \times 10^{-3}$
- C$1 \times 10^{-5}$
- D$2 \times 10^{-5}$
