Nitric oxide (NO) can be formed from nitrogen, hydrogen and oxygen in two steps. In the first step, nitrogen and hydrogen react to form ammonia:
N2(g) + 3H2(g) →2NH3(g)
ΔH=−92.kJ
In the second step, ammonia and oxygen react to form nitric oxide and water:
4NH3(g) + 5O2(g) → 4NO(g) +6H2O(g)
ΔH=−905.kJ
Calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions.
