How many moles of NO can be formed when 2.86 mol of N2 reacts?

At elevated temperatures in an automobile engine, N2 and O2 can react to yield NO, an important cause of air pollution.

5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.

Explanation:

Given dа ta:

Moles of NO formed = ?

Moles of N₂ reacts = 2.86 mol

Solution:

Chemical equation:

N₂ + O₂ → 2NO

Now we will compare the moles of nitrogen with nitrogen oxide from balance chemical equation.

N₂ : NO

1 : 2

2.86 : 2/1*2.86 = 5.72 mol

So 5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
