Low-Emission Vehicles Adding ammonia to the exhaust gases from motor vehicles can reduce the emissions of nitrogen oxide pollutants through selective catalytic reduction (SCR):
6 NO(g) + 4 NH₃(g) →5 N₂(g) + 6 H₂O(g) ΔΗχη = AHex -1807
6 NO₂(g) + 8 NH₃(g) → 7 N₂(g) + 12 H₂O(g) ΔΗχη = AHex -2730 kJ
Determine the value of the heat of reaction for the following:
3 NO(g) + N₂(g) + 3 H₂O(g) → slow 3 NO₂(g) + 2 NH₃(g)
AHpx = ? kJ
