Is the fission of a `._26^56Fe` nucleus into two equal fragments , `._13^28Al` energetically possible ? Argue by working out Q of the process. Given , `m(._26^56Fe )` = 55.93494 u and `m(._13^28Al)` = 27.98191 u

Text Solution

Verified by Experts

If possible , let the reaction be, `._26^56Fe to ._13^28Al + ._13^28Al`
Q-value of the process =`m(._26^56Fe) -2m(._13^28Al)`
=55.934944- 2 x 27.98191
=-0.02888 x 931.5 MeV
=-26.90 MeV
Since the Q-value is negative, fission is not possible .
