Question

In the reaction N₂(g) + 3H₂(g) → 2NH₃(g), if you have 1 molecule of N₂ and 5 molecules of H₂, how many molecules of excess reagent remain?
Options
A 1 molecule
B 2 molecules
Correct Answer
C 3 molecules
D 4 molecules
Correct Answer

Option B is the correct answer.

Detailed Explanation

The reaction requires 3 molecules of H₂ for 1 molecule of N₂. With 5 molecules H₂ available, 5 - 3 = 2 molecules of H₂ remain as excess reagent.
