If a mixture containing 0.50 moles of N2 and 1.8 moles of H2 is allowed to react according to the equation N2 3H2 2NH3 Group of

Lelechka [254]

Answer: hydrogen is the limiting reactant.

Explanation:

We have the equation $\text{N}_{2}+3\text{H}_{2} \longrightarrow 2\text{NH}_{3}$ .

This means that for every mole of nitrogen consumed, 3 moles of hydrogen are consumed.

Considering the nitrogen, the reaction can occur 0.50 times.
Considering the hydrogen, the reaction can occur 1.8/3 = 0.6 times.

Therefore, <u>hydrogen</u> is the limiting reactant.
