QUESTION 5 Nitrogen monoxide, released from the combustion engines of motor vehicles, reacts with oxygen in the atmosphere to produce nitrogen dioxide. This reaction can be simulated in a closed reaction container of volume 500 cm' at a temperature of 100 °C. The reaction reaches equilibrium according to the following chemical equation: 2NO(g) + O2(g) 2NO2(g) Initially 4 mol of NO and 2,5 mol of O2 were placed in the reaction container with an unknown amount of NO2. When equilibrium was established, it was found that the concentration of NO present in the reaction container was 6,5 mol dm. The equilibrium constant, Ke, for the reaction at 100 °C is 0,25. 5.1 State Le Chatelier's Principle. A chemical equilibrium occurs in a 'closed system'. State what is meant by the term 'closed system'. 5.2 5.3 Calculate the number of moles of NO present at equilibrium.
