Le Chatelier's principle states changes in equilibrium such as factors like temperature and concentration changes. To increase the molar concentration of N2O4 (g), 2NO2 (g) should also increase for equilibrium to occur. Now, this equation is exothermic. By Le Chatelier's principle, equilibrium constant and reaction constants also come into play in terms of increasing or decreasing the temperature.
