Limiting reagent: making water
Mix hydrogen and oxygen gas and find which runs out first in 2H₂ + O₂ → 2H₂O.
What to notice
The reactant that is used up first limits the amount of product; the other is left over in excess.
Key relation
2 H₂ + O₂ → 2 H₂O ; n(H₂O) = min(n(H₂), 2 n(O₂))
Try this
Use 4 g H₂ and 16 g O₂. Which one is limiting?
What you can change
- Hydrogen taken: 0.5 to 10 g
- Oxygen taken: 4 to 80 g
- Reaction progress: 0 to 100 %
