Question

For a reaction, $N_2(g) + 3H_2(g) \rightarrow 2NH_3(g)$; identify dihydrogen $(H_2)$ as a limiting reagent in the following reaction mixtures.

• A. $14g$ of $N_2$ + $4g$ of $H_2$
• B. $28g$ of $N_2$ + $6g$ of $H_2$
• C. $56g$ of $N_2$ + $10g$ of $H_2$
• D. $35g$ of $N_2$ + $8g$ of $H_2$

Answer 1

Answer: (C)

$56g$ of $N_2$ + $10g$ of $H_2$

Answer 2

$N_2(g) + 3H_2(g) \rightarrow 2NH_3$(g)
(1) $^{0.5 \, mol}_{(LR)}\, 2\, mol$
(2) $1 \,mol\, 3 \,mol\, (completion)$
(3) $2 \,mol \,_{(LR)}^{5 \, mol}$
(4) $_{(LR)}^{1.25} \,mol\, 4\, mol$
