The equilibrium constant for the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2NO_{(g)}$ is $4 \times 10^{-4}$ at $2000 \ K$. In the presence of a catalyst,the equilibrium is attained ten times faster. Therefore,the equilibrium constant in the presence of a catalyst at $2000 \ K$ is:
- A$4 \times 10^{-3}$
- B$4 \times 10^{-2}$
- C$4 \times 10^{-3}$
- D$4 \times 10^{-4}$
