Chemistry 12 Unit 2 Notes - Equilibrium Unit 2 Notes – Equilibrium Page 3 Now what we're going to do is look at how the rate of the forward reaction changes if we put some pure N2O4 in a flask: If we put some pure N2O4 in a flask (No NO2 yet!), there will be a high concentration of N2O4. That is, there will be lots of N2O4 molecules to collide with each other.
