Q16 of 37 Page 1

Which physical quantity in a nuclear reaction is considered equivalent to the Q- value of the reaction?

The conservation of energy, between the initial and final energy of a nuclear process ({displaystyle E_{ ext{i}}=E_{ ext{f}}}), enables the general definition of Q based on the mass–energy equivalence. For any radioactive particle decay, the kinetic energy difference will be given by

{displaystyle Q=K_{ ext{f}}-K_{ ext{i}}=(m_{ ext{i}}-m_{ ext{f}})c^{2}}


So, kinetic energy is the physical quantity in a nuclear reaction is considered equivalent to the Q- value of the reaction.
