Answer to Question #143372 in General Chemistry for Aj

Question

The reaction N2(g) + 2O2(g) ! N2O4(g) occurs in a closed
container. If 8.0 moles N2(g) are made to react with 12.0 moles
O2, the limiting reagent and the theoretical yield of N2O4 are:

Answer 1

Solution:

According to the reaction equation for 1 mol of N₂ are needs 2 moles of O₂.

Therefore, for 8.0 moles N₂ are needs 16 moles O₂.

The limiting reagent is O₂.

The theoretical yield of N₂O₄ is 6 moles.

Answer: The limiting reagent is O₂. The theoretical yield of N₂O₄ is 6 moles.
