Glass sealed NO2 As the temperature rises pastThis is used to demonstrate how temperature affects chemical equilibrium. In the sealed tube, NO2 and N2O4 interconvert: 2 NO2(g) N2O4(g) Their ratio changes with temperature, producing different colors (more NO2 gives a brown color; more N2O4 gives a colorless pale appearance). Its a classic equilibrium demonstration. You can see an example here: https: www. youtube. com watch? v=Vt9HyDnTZ6E Shipping We ship worldwide and handle all import and
