N2O4(g)= 2NO2(g), what would happen if: more N2O4 is added to the system?

Answer 1

If more N2O4 is added to the system, Le Chatelier's principle predicts that the equilibrium will shift towards the right to relieve the stress of the increased concentration of N2O4. This means that more N2O4 will be consumed and more NO2 will be produced until a new equilibrium is reached. This will result in an increase in the concentration of NO2 and a decrease in the concentration of N2O4 in the system.
