Consider the reaction
\[
\mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(\mathrm{~g}) \rightarrow 2 \mathrm{NH}_{3}(\mathrm{~g})
\]
The equality relationship between \( \frac{\mathrm{d}\left[\mathrm{NH}_{3}\right]}{\mathrm{dt}} \) and \( -\frac{\mathrm{d}\left[\mathrm{H}_{2}\right]}{\mathrm{dt}} \) is
(a) \( +\frac{\mathrm{d}\left[\mathrm{NH}_{3}\right]}{\mathrm{dt}}=-\frac{2}{3} \frac{\mathrm{d}\left[\mathrm{H}_{2}\right]}{\mathrm{dt}} \)
(b) \( +\frac{\mathrm{d}\left[\mathrm{NH}_{3}\right]}{\mathrm{dt}}=-\frac{3}{2} \frac{\mathrm{d}\left[\mathrm{H}_{2}\right]}{\mathrm{dt}} \)
(c) \( \frac{\mathrm{d}\left[\mathrm{NH}_{3}\right]}{\mathrm{dt}}=-\frac{\mathrm{d}\left[\mathrm{H}_{2}\right]}{\mathrm{dt}} \)
(d) \( \frac{\mathrm{d}\left[\mathrm{NH}_{3}\right]}{\mathrm{dt}}=-\frac{1}{3} \frac{\mathrm{d}\left[\mathrm{H}_{2}\right]}{\mathrm{dt}} \)
