Question

For nuclear fusion H-2 + H-3 → He-4 + n, the binding energies of H-2, H-3 and He-4 are a, b and c (MeV). The energy released is:

G1 Physics · Accepted Answer

Q = total binding energy of products − total binding energy of reactants. The free neutron has zero nuclear binding energy. Thus Q = c − (a + b) = c − a − b. Final answer: Option C.
