Answer:
NH₃ is limiting reactant .
Explanation:
Given data:
Number of moles of NH₃ = 45 mol
Number of moles of NO₂ = 50 mol
Limiting reactant = ?
Solution:
Chemical equation:
8NH₃ + 6NO₂ → 7N₂ + 12H₂O
Now we will compare the mole of reactants with products.
NH₃ ; N₂
8 : 7
45 : 7/8×45 = 39.4 mol
NH₃ ; H₂O
8 : 12
45 : 12/8×45 = 67.5 mol
NO₂ ; N₂
6 : 7
50 : 7/6×50 = 58.3 mol
NO₂ ; H₂O
6 : 12
50 : 12/6×50 = 100 mol
Less number of moles of product are formed by the ammonia thus it will be limiting reactant.
