$N_{2(g)} + 3H_{2(g)} \rightarrow 2NH_{3(g)}$ The equality relationship between $\frac{d[NH_3]}{dt}$ and $\frac{d[H_2]}{dt}$ is

$CHCl_3\xrightarrow[hv]{O_2}[A]\xrightarrow{EtOH}[B]\xrightarrow{2\ mole\ MeMgBr}$

$[C]\xrightarrow{CaOCl_2}[D]\xrightarrow{\Delta}CH_3-\underset{\underset{O}{||}}{C}-CH_3$
