The standard enthalpy of combustion of propane, C3Hg, is -2.220 x 103 kJ mol-1 at 400 K. Use the data below, and Kirchhoff's law, to calculate the standard enthalpy of combustion at 600 K. The reaction involved is: C3H8 (g) + 5 O2(g) → 3 CO2(g) + 4H₂O(g) Cp,m (J K-1 mol-1): C3H8 (g) = 73.6; O2(g) = 29.4; H₂O(g) =33.6; CO2(g) =37.1 -3395 kJ mol-1 - 2195 kJ mol-1 2595 kJ mol-1 500 kJ mol-1

The standard enthalpy of combustion of propane, C3Hg, is -2.220 x 103 kJ mol-1 at 400 K. Use the data below, and Kirchhoff's law, to calculate the standard enthalpy of combustion at 600 K. The reaction involved is: C3H8 (9) + 5 O2(g) → 3 CO2(g) + 4H₂O(g) Cp,m (J K-1 mol-1): C3H8 (g) = 73.6; O2(g) = 29.4; H₂O(g) =33.6; CO2(g) =37.1 -3395 kJ mol-1 - 2195 kJ mol-1 2595 kJ mol-1 500 kJ mol-1

An important industrial chemical process is the production of nitric acid. One of the important step in the synthesis of nitric acid is the conversion of ammonía to nitric oxide: 4NH3(g) + 502(g) →→ 4NO(g) + 6H₂O(g) Calculate Hºrxn for this reaction. Given the following data: Hᵒf [NH3(g)] = -45.9 kJ/mol; Hᵒf [NO(g)] = 90.3 kJ/mol; Hᵒf [H2O(g)] = -241.8 kJ/mol -105.6 kJ O-906.0 kJ 197.4 kJ -197.4 kJ
