Nitric oxide (nitrogen monoxide) gas can be oxidized in air to produce nitrogen dioxide Use Hess's Law to determine the enthalpy of reaction when this compound reacts as follows:
Target Equation: 2N2(g) + 5O2(g) ® 2N2O5(g)
Use the following information:
1. N2O5(g) + H2O(l) ® 2 HNO3(l) DH° = -77 kJ
2. N2(g) + 3O2(g) + H2(g) ® 2 HNO3(l) DH° = -174 kJ
3. 2H2(g) + O2(g) ® 2H2O(l) DH° = -572 kJ
