In the reaction 12H + 13H ®24He + 01n. If the binding energies of 12H, 13H and 24He are respectively a, b and c (in MeV), then the energy (in MeV) released in this reaction is –
A
c + a – b
B
c – a – b
C
a + b + c
D
a + b – c
Answer
c – a – b
Explanation
Solution
E = B.E.Product – B.E.Reactant
= (B.E.2He4 + B.E.0n1) – (B.E.1H2 + B.E.1H3)
= (c + 0) – (a + b)
= c – (a + b)
E=c−a−b
