CHM 101 Stoichiometry of Chemical Reactions Objective Question

Question

In the reaction N₂(g) + 3H₂(g) → 2NH₃(g), if you have 1 molecule of N₂ and 5 molecules of H₂, which is the limiting reagent?
Options
A N₂ is limiting
Correct Answer
B H₂ is limiting
C Both are limiting
D NH₃ is limiting
Correct Answer

Option A is the correct answer.

Detailed Explanation

From the balanced equation, 1 molecule of N₂ requires 3 molecules of H₂. Since there are 5 molecules of H₂ available (more than needed), N₂ is the limiting reagent.

Hint

The notes pose a similar question about identifying limiting reagent.
