For the reaction given below, how many moles of nitrogen monoxide will form if we start with 2.0 moles of oxygen?


4 NH3 + 5 O2 → 4 NO + 6 H2O


5.0 mol

2.5 mol

2.0 mol

4.0 mol

1.6 mol


Sagot :

Answer: 1.6 mol (option 5)

Explanation:

Mole Ratio of O₂ : NO

Based on the balanced equation, the mole ratio of O₂ : NO is 5 : 4

∴ for every mole of O₂ reacted, ⁴/₅ moles of NO is produced

Moles of NO

since the number of mol of O₂ =  2.0 mol

   then moles of NO produced = 2.0 mol × ⁴/₅

                                                   =  1.6 mol

∴ the moles of nitrogen monoxide that will form if we start with 2.0 moles of oxygen is 1.6 mol (option 5).
