Energy absorbed;
ΔQ=Binding energy of products - Binding energy of reactants
Binding energy of products
=2×(B.E of He4)+(B.E of C12)
=2(4×7.07)+(12×7.86)
=150.88 MeV
Binding energy of Reactants = 20×8.03=160.6 MeV
ΔQ=Binding energy of products - Binding energy of reactants=150.88−160.6=−9.72 MeV
Hence, 9.72 MeV energy will be released
