Isooctane C8H18 is a major component of gasoline. Determine the change in enthalpy for the combustion of 2.000 mol of isooctane from the following data:

H2( g) + (1/2)O2 (g) ⟶ H2O(g) ΔH0 = −241.8 kJ
C (s) + O2 (g)⟶ CO2 (g) ΔH0 = −393.5 kJ
8C (s) + 9H2 (g) ⟶ C8H18 (l) ΔH0 = −224.13 kJ

Choices:

−5548 kJ

-89.43 kJ

−10200 kJ

−2550 kJ

-411.2 kJ
