Question

The energy released (Q value) in the fission reaction of nuclei like uranium is of the order of:

Options

• 2000 MeV per fissioning nucleus

• 200 MeV per fissioning nucleus

• 20 MeV per fissioning nucleus

• 2 MeV per fissioning nucleus

Answer 1

The energy released, or Q value, in the fission reaction of nuclei like uranium is of the order of 200 MeV per fissioning nucleus, consistent with the estimated gain in binding energy of about 216 MeV.
