C8H18 (l) + 25 O2 (g) → 8 CO2 (g) + 9 H2O (g) ΔH°rxn = -5074.1 kJ
The world burns the fossil fuel equivalent of 3×1012 kg of petroleum per year. Assume that all of this petroleum is in the form of octane (C8H18).
(a) If the atmosphere currently contains approximately 3x1015 kg CO2, how long will it take for the world's fossil fuel combustion to double the amount of atmospheric carbon dioxide?
