Question

$N_2+3H_2\to 2{NH}_3$
If $2mol$ of $N_2$ and $5mol$ of $H_2$ are available for the reaction shown above, what is the limiting reactant?

• A. All reactants will be completely used up.
• B. $N_2$
• C. $H_2$
• D. ${NH}_3$

Answer 1

The correct option is C $H_2$

$N_2+3H_2\to 2N{H}_3$

$250$

$\frac{1}{3}moles0\frac{10}{3}moles$

Limiting reagent in a chemical reaction is a substance that is totally consumed when the chemical reaction is complete.

Here, hydrogen is limiting agent because it gets consumed during the course of reaction.
