Problem Details

Given the following data: 

N2(g) + O2(g) → 2NO(g),          ΔH = +180.7 kJ 

2NO(g) + O2(g) → 2NO2(g),     ΔH = -113.1 kJ 

2N2O(g) → 2N2(g) + O2(g),      ΔH = -163.2 kJ 

Use Hess's law to calculate ΔH for the following reaction: 

N2O(g) + NO2(g) → 3NO(g) 

Express the enthalpy in kilojoules to four significant digits.
