The standard enthalpy of combustion of propane, C3H8, 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) + 4 H₂O(g) Cp,m (J K-1 mol-1): C3H8 (g) = 73.6; O2(g) = 29.4; H₂O(g) =33.6; CO2(g) =37.1 O 500 kJ mol-1 O-2195 kJ mol-1 O -3395 kJ mol-1 O 2595 kJ mol-1

Question
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) + 4 H₂O(g)
Cp,m (J K−1 mol¯¹): C3H8 (g) = 73.6; O2(g) = 29.4; H₂O(g) =33.6; CO2(g) =37.1
500 kJ mol-1
O-2195 kJ mol-1
-3395 kJ mol-1
2595 kJ mol-1
