2. The standard enthalpies of the following combustion reactions have been determined experimentally
C;H6 (g) +02 (g) → 2 CO2 (g) + 3 H¿O (1)
C (s) + O2 (g) → CO2 (g)
H: (g) +O: (g) → H;0 (1)
AH,° = -1559.8 kJ/mol
AH,º = -393,5 kJ/mol
AH° = -285.8 kJ/mol
Use Hess' law and the given heats of reaction to determine the standard heat of the following reaction
2 C (s) + 3 H2 (g) → C¿H6 (g)
