How does increasing the pressure on this system affect the amount of n204 formed?

Increasing the pressure on a system involving the equilibrium between dinitrogen tetroxide (N₂O₄) and nitrogen dioxide (NO₂) can shift the equilibrium position according to Le Chatelier's principle. If the reaction involves a decrease in the number of gas molecules, such as the formation of N₂O₄ from NO₂, the increased pressure will favor the production of N₂O₄. Thus, more N₂O₄ will be formed under higher pressure conditions, provided that the temperature remains constant.
