In the reversible reaction between nitrogen dioxide (NO2, reddish-brown) and dinitrogen tetroxide (N2O4, colorless), heat energy shifts the equilibrium toward NO2, making the gas appear darker, while cooling shifts it toward N2O4, making it lighter; this demonstrates Le Chatelier's Principle in action.

Heat energy shifts the balance between these two gases. [music] Reddish-brown NO2 dominates with heat, while cooling favors colorless N2O4.
[music] Physics fans, if I increase the pressure, does it get darker or lighter?
