1. Write the balanced equation for the production of brown nitrogen dioxide (NO2) gas from nitrogen and oxygen gases. Calculate the enthalpy of the reaction if the process occurs in the sequence of reactions given below:
  • N2 (g) + O2 (g) —> 2NO (g)           ∆H = 180 kJ
  • 2NO2 (g) —> 2NO (g) + O2 (g)       ∆H = 112 kJ
