Question
The binding energy per nucleon of 
and 
nuclei are 5.60 MeV and 7.06 MeV, respectively. In the nuclear reaction 
Li + 
H → 
He + He + Q, the value of energy Q released is
and nuclei are 5.60 MeV and 7.06 MeV, respectively. In the nuclear reaction Li + H → He + He + Q, the value of energy Q released isOptions
A.19.6 MeV
B.-2.4 MeV
C.8.4 MeV
D.17.3 MeV
Solution
Q = 2(BE of He) - (BE of Li)
= 2 × (4 × 7.06) - (7 × 5.60)
= 56.48 - 39.2 = 17.3 MeV
= 2 × (4 × 7.06) - (7 × 5.60)
= 56.48 - 39.2 = 17.3 MeV
