Dinitrogen tetraoxide and nitrogen dioxide are two gases that exist in equilibrium ata range of temperatures. NO2 is a reddish brown gas while N2O4 is colorless. Athigh temperatures the red color is strong. At low temperatures the gas has less color.If we represent the equilibrium as, N2O4(g)We can conclude that the reaction is2 NO2(g) 2 NO2(g) N₂O(g)Brown gasColorless gasCannana laminaMama CaExothermicEndothermicNeutralMore information is needed to answer this question
