Question
In a nuclear reaction, the product nucleus has higher
binding energy per nucleon than the reactants. Which of the following is correct?Solution
If the binding energy per nucleon of the product nucleus is higher than that of the reactants, it means the product is more stable. The total binding energy increases, and the mass of the final nucleus is less than the mass of the initial system. This mass difference is released as energy, known as the Q-value of the reaction. Therefore, such a process is exothermic, and energy is released.
