c) both
d) hydrogen

Answer 1

Answer:

a) nitrogen

hope it helps ☺️

Answer 2

The correct option is (a) Nitrogen

Explanation:

The limiting reagent is one that reacts completely in the process . Excess reagent is a reactant that is not completely consumed in a reaction.

In the given question ,

112g of nitrogen reacts with 30g of hydrogen ,

$N_{2}$ + $3H_{2}$ ⇄ $2NH_{3}$

$H_{2}$ is totally consumed in the haber process, whereas $N_{2}$ is in excess.

Therefore, nitrogen will be excess reagent in this reaction.
