For three nuclei with mass numbers $3$ , $4$ and $5$ , the binding energy per nucleon are $5.3 MeV$ , $6.2 MeV$ and $7.4 MeV$ respectively. If one nucleus of mass number $3$ combines with another nucleus of mass number $5$ to give two nuclei of mass number $4$ , then

Options:

Answer:

Solution:

$X^{3} + Y^{5} ⟶ 2 Z^{4}$

$∆ E = (3 \times 5 .3 + 5 \times 7 .4) - 2 (4 \times 6 .2) = 3 .3 MeV$

since $∆ E$ is positive, energy is absorbed
