# How to find NO2 at equilibrium? Watch

1. 2NO2 <=>N2O4

A chemist investigating this reaction started with 10 moles of NO2 and allowed the system to reach equilibrium.

If 3 mole of N2O4 are formed the number of moles of NO2 at equilibrium is???

How many moles of NO2 have to react to form 1 mol of N2O4?

20 moles? because started with ten but NO2 has a big 2 in front.

From the equation you need to react 2 moles of NO2 together to get 1 mole of N2O4

Therefore if 3 mol of N2O4 are formed ....
