Ammonia is prepared industrially by the following reaction: N2(g) + 3H2(g) ⇌ 2NH3(g)    ΔH° = –92.2 kJ/mol For this reaction, K = 4.0×108 at 25°C. When the temperature of the reaction is increased to 500°C, which of the following statements is true? Select one: No shift will occur since heat is not included in the equilibrium expression. The equilibrium constant will increase. The partial pressure of N2 will increase. Product formation is favoured. The value of K will not change.
