Quizplus · Accepted Answer

The Q-value of a reaction is the difference in the total rest mass energy of the products and the reactants. Here, the initial rest mass energy is 2 * 938 MeV (for the two protons), and the final rest mass energy is 2 * 938 MeV + 135 MeV (for the two protons and the neutral pion). The Q-value is therefore 2 * 938 - (2 * 938 + 135) = -135 MeV.
