The following two-step process can be used to produce NO₂:
N₂ + O₂ $\rightarrow$ 2NO
O₃ + NO $\rightarrow$ O₂ + NO₂
If 25.0 moles of NO₂ were produced, how many moles of N₂ were used to initiate the sequence of reactions?

Question

The following two-step process can be used to produce NO₂:
N₂ + O₂

\rightarrow

2NO
O₃ + NO

\rightarrow

O₂ + NO₂
If 25.0 moles of NO₂ were produced, how many moles of N₂ were used to initiate the sequence of reactions?

Quizplus · Accepted Answer

In the first reaction, 1 mole of N₂ produces 2 moles of NO. In the second reaction, 1 mole of NO produces 1 mole of NO₂. Therefore, to produce 25.0 moles of NO₂, 25.0 moles of NO are needed, which requires 12.5 moles of N₂.
