The binding energy per nucleon of deuteron (12H)\left({ }_1^2 \mathrm{H}\right) and helium nucleus (24He)\left({ }_2^4 \mathrm{He}\right) is 1.1MeV1.1 \mathrm{MeV} and 7MeV7 \mathrm{MeV} respectively. If two deuteron nuclei react to form a single helium nucleus, then the energy released is

Options

  1. A13.9MeV13.9 \mathrm{MeV}
  2. B26.9MeV26.9 \mathrm{MeV}
  3. C23.6MeV23.6 \mathrm{MeV}
  4. D19.2MeV19.2 \mathrm{MeV}

Correct answer

C. 23.6MeV23.6 \mathrm{MeV}

Step-by-step solution

Energy released = total binding energy of product −- total binding energy of reactants ⇒28−(2×2.2)=28−4.4=236MeV\Rightarrow 28-(2 \times 2.2)=28-4.4=236 \mathrm{MeV}
