Consider the reaction: $N_{2(g)} + 3H_{2(g)} \rightarrow 2NH_{3(g)}$. The equality relationship between $\frac{d[NH_3]}{dt}$ and $\frac{d[H_2]}{dt}$ is
- A$\frac{d[NH_3]}{dt} = - \frac{d[H_2]}{dt}$
- B$\frac{d[NH_3]}{dt} = - \frac{1}{3} \frac{d[H_2]}{dt}$
- C$+ \frac{d[NH_3]}{dt} = - \frac{2}{3} \frac{d[H_2]}{dt}$
- D$+ \frac{d[NH_3]}{dt} = - \frac{3}{2} \frac{d[H_2]}{dt}$
