A nuclear fusion reaction is given by

4\left( {{}_2^4He} \right) \to {}_8^{16}O

. If atomic mass of He is 4.0026 amu and that of O is 15.9994 amu then the Q-value of the reaction will be approximately

View answer and explanation

Correct option: B

10.2 MeV

Option B (10.2 MeV) is correct because the Q-value is calculated by finding the difference in mass between the reactants and products and then converting it to energy using

E=mc^2
