Octane (C8H18) undergoes combustion according to the following thermochemical equation:
         2C8H18(l) + 25O2(g) → 16CO2(g) + 18H2O(l)       ΔH°rxn = –11,020 kJ/mol.
Given that ΔH°f[CO2(g)] = –393.5 kJ/mol and ΔH°f[H2O(l)] = –285.8 kJ/mol, calculate the standard enthalpy of formation of octane.
◦ –210 kJ/mol
◦ –11,230 kJ/mol
◦ 22,040 kJ/mol
◦ –420 kJ/mol
◦ 420 kJ/mol
