1. Write the balanced equation for the production of the brown nitrogen dioxide (NO2) gas from nitrogen and oxygen gases. Calculate the enthalpy of the reactions given below. N2 (g) +O2 2NO (g) 2NO (g) AH = 180 kJ ne 2NO(g) +Q2 (g) AH = 112 kJ 2. Methylhydrazine (N2H3CH3) is common liquid propellant used in rocket fuels. Look for the standard molar enthalpies of formation of the reactants and products. Calculate the AH° for the reaction per mole of N2H3CH3. 4N2H3CH3 (1) + 5N2O4 () 12H20 (g) +9N2 (g) +4CO2 (g)

SAMPLE PROBLEMS: rimsts 1. Using the standard molar enthalpies of formation given, calculate the standard enthalpy of reaction for the combustion of propane (C3He) into carbon dloxide and water. C3HB (g) + 502 (g) +3CO2 (g) + 4H20 (g) CaHa (g) -104.0 CO2 (g) -393.5 H20 (g) -241.8 O2 (g) Substance AH°: (kJ/mol) Solution: CM EAH°nm = [3AH°r (CO2, g) +4AH°, (H20, g)]-[AH°: (C3Ha, g) +5AH°; (O2, g)] =[3(-393,5 kJ) +(-241.8 kJ)] – [(-104.0 kJ) + 5 () = -2043.7 kJ 2. The thermochemical equation for the incomplete combustion of carbon into carbon monoxide is represented as 20 (s) +O2 (9) → 200 (g) Compute for the AH of the reaction if the overall process above can occur in two steps whose themochemical equations are given below: (1) C (s) +O2 (g) (2) 2CO (g) +O2 (9) CO2 (g) 2C02 (g) AH = -393.5 kJ AH = -566.0kJ
