Answer:
1) Maximun ammount of nitrogen gas:
2) Limiting reagent:
3) Ammount of excess reagent:
Explanation:
<u>The reaction </u>
Moles of nitrogen monoxide
Molecular weight:
Moles of hydrogen
Molecular weight:
Mol rate of H2 and NO is 1:1 => hydrogen gas is in excess
1) <u>Maximun ammount of nitrogen gas</u> => when all NO reacted
2) <u>Limiting reagent</u>:
3) <u>Ammount of excess reagent</u>:
