The binding energy of deuteron 1H2 is 1.112 Me V per nucleon and an α-particle 2He4 has a binding energy of 7.047 Me V per nucleon. Then in the fusion reaction 1H2 + 1H2 → 2He4 + Q , the energy Q released is

Q: The binding energy of deuteron ₁H² is 1.112 Me V per nucleon and an α-particle ₂He⁴ has a binding energy of 7.047 Me V per nucleon. Then in the fusion reaction ₁H² + ₁H² → ₂He⁴ + Q , the energy Q released is

(a) 1 Me V

(b) 11.9 Me V

(c) 23.8 Me V

(d) 931 Me V

Sol: (c) Q – value = 4 × 7.04-4 × 1.112 = 23.74 Me V
