2.0 mol of N₂ and 2.0 mol of H₂ react via N₂ + 3H₂ → 2NH₃. How many moles of H₂ remain after complete reaction?
A.0.0 mol (H₂ is limiting)
B.0.67 mol
C.1.0 mol
D.2.0 mol
Explanation
Core Concept
2.0 mol N₂ would need 6.0 mol H₂; only 2.0 mol is present, so H₂ runs out first. The limiting reactant is fully consumed, leaving excess N₂.
Correct Answer
A0.0 mol (H₂ is limiting)
