LE CHATELIER'S PRINCIPLE
SEQUENCE, SERIES
NO2 & N2O4 - TEMPERATURE
As the NO2 gas reaches an equilibrium of N2O4(g)=2NO2(g) at room temperature it turns a deep red-brown.
NO2 & N2O4 - TEMPERATURE
Liquid NO2
The equilibrium of N2O4(g)=2NO2(g) moves to the right when the test tube is warmed and the frozen NO2 melts to a liquid. The concentration of red-brown Nitrogen dioxide gas (NO2) increases and the color darkens.
Frozen Solid NO2
