Limiting ReagentEasyQuestion 600022

Question

In N₂ + 3H₂ → 2NH₃, if 1 mol N₂ and 2 mol H₂ are taken, the limiting reagent is:
  1. A
    N₂
  2. B
    H₂
    Correct
  3. C
    NH₃
  4. D
    Both are limiting

Correct answer

H₂

Explanation

To consume 1 mol N₂, we need 3 mol H₂. Only 2 mol H₂ available → H₂ is limiting. H₂ runs out first.
