When carbon burns to produce carbon dioxide,395 kJ/mol of energy is released.Approximately how much greater is the energy released per mole of deuterium in the following fusion process: 2 ²H $\to$⁴He? The atomic masses are 2.0141 g/mol for ²H and 4.0026 g/mol for ⁴He.(1 kJ = 1000 kg m²/s²)

Question

Quizplus · Accepted Answer

Energy released per mole of carbon in the combustion reaction = 395 kJ/molEnergy released per mole of deuterium in the fusion reaction = (2 × 3.02 × 10⁸ kJ/mol) / 2 = 3.02 × 10⁸ kJ/molTherefore, the energy released per mole of deuterium in the fusion reaction is approximately 3.02 × 10⁸ kJ/mol / 395 kJ/mol = 7648 times greater than the energy released per mole of carbon in the combustion reaction.Hence, the correct choice is C) 10⁶.
