Question

What amount of energy is released by deuterium and tritium fusion?

(a) 60.6 eV

(b) 12.6 eV

(c) 17.6 eV

(d) 28.33 eV

I have been asked this question in final exam.

I'd like to ask this question from Nuclear Energy in portion Nucleus of Physics – Class 12

Answer 1

The correct option is (c) 17.6 eV

To elaborate: 1H^2 + 1H^3 ➔ 2He^4 + 0n^1 + Q.

= [2.014 + 3.016 – 4.002 – 1.008] × 931.5 MeV.

= 17.6 MeV.
