Question

The binding energy energies of deuteron  and -particle  are 1.112 and 7.07 MeV/nucleon respectively. Find out in the process , state whether energy is supplied or liberated and how much? 

Solution

Correct option is

23.8 MeV

Let us consider the nuclear reaction : 

              

Deuteron  has 2 nucleons. So, binding energy of deuteron

       

       

 has 4 nucleons. So, binding energy of  is 

          

Thus, , in comparison to , has  more binding energy. So, 23.8 MeV energy will be liberated in this process.
