According to the balanced equation, 2 moles of octane (C8H18) produce 1.02 x 10^4 kJ of heat. Therefore, per mole of octane, the amount of heat produced would be:
(1.02 x 10^4 kJ) / 2 = 5.1 x 10^3 kJ
0. A common gasoline additive is octane, C8H18. When octane is burned it produces heat
according to the following equation.
2C8H18(l) + 25O2
(g) → 18H2O(g) + 16CO2
(g) ΔH = 1.02 x 10
