- #16Suppose, we think of fission of a
nucleus into two equal fragments,
. Is the fission energetically possible? Argue by working out Q of the process. Given
and
.
Ans : The fission of
can be given as:

It is given that:
Atomic mass of
= 55.93494 u
Atomic mass of
The Q-value of this nuclear reaction is given as:

The Q-value of the fission is negative. Therefore, the fission is not possible energetically. For an energetically-possible fission reaction, the Q-value must be positive.
