Consider the reaction

$2N{H}_3(g)N_2(g)+3H_2(g)$

If the rate $\frac{H_2}{}t$ is $0\mathrm{.}030mol{L}^{-1}{s}^{-1},$ then $\frac{N{H}_3}{}t$ is

$-0\mathrm{.}045mo\frac{l}{L}s$

$-0\mathrm{.}030mo\frac{l}{L}s$

$-0\mathrm{.}020mo\frac{l}{L}s$

$-0\mathrm{.}010mo\frac{l}{L}s$

None of these choices are correct
