If you feed 100 kg of N2 gas and 100 kg of H2 gas into a reactor. What is the limiting reactant?
1 answer:
Answer:
N₂ is the limiting reactant
Explanation:
The balanced reaction between N₂ gas and H₂ gas is:
N₂ + 3H₂ → 2NH₃
In order to determine the limiting reactant, we have to <u>calculate the number of moles of each rectant</u>, using their molecular weight:
- Moles of N₂= 100 kg *
= 3.57 kmol
- Moles of H₂= 100 kg *
= 50.0 kmol
Lastly, we multiply the number of moles of N₂ by 3, and the number of moles of H₂ by 1; due to the coefficients in the balanced reaction. Whichever number is lower, belongs to the limiting reactant.
N₂ => 10.7
H₂ => 50.0
Thus N₂ is the limiting reactant

Explanation:
Sodium hypochlorite is a corrosive base with pH 13, that will react with water in a neutralization process to finally obtein hypochlorous acid. This acid has a great disinfectant effect in water.
Reactant C is the limiting reactant in this scenario.
Explanation:
The reactant in the balanced chemical reaction which gives the smaller amount or moles of product is the limiting reagent.
Balanced chemical reaction is:
A + 2B + 3C → 2D + E
number of moles
A = 0.50 mole
B = 0.60 moles
C = 0.90 moles
Taking A as the reactant
1 mole of A reacted to form 2 moles of D
0.50 moles of A will produce =
thus 0.50 moles of A will produce 1 mole of D
Taking B as the reactant
2 moles of B reacted to form 2 moles of D
0.60 moles of B reacted to form x moles of D
=
x = 2 moles of D is produced.
Taking C as the reactant:
3 moles of C reacted to form 2 moles of D
O.9 moles of C reacted to form x moles of D
=
= 0.60 moles of D is formed.
Thus C is the limiting reagent in the given reaction as it produces smallest mass of product.
