The Q value of a nuclear reaction,

A + b \to C + d

is defined by

Q = [m_{A} + m_{b}] - [m_{C} + m_{d}]

where, the masses refer to the respective nuclei. Determine from the given data the Q-value of the following reactions and state whether the reactions are exothermic or endothermic.
(i)

_{1}^{1} H +_{3}^{1} H \to_{1}^{2} H +_{1}^{2} H

(ii)

_{6}^{12} C +_{6}^{12} C \to_{10}^{20} Ne +_{2}^{4} He

Atomic masses are given to be

m (_{1}^{2} H) = 2.014102 u m (_{1}^{3} H) = 3.016049 u m (_{6}^{12} C) = 12.000000 u m (_{10}^{20} Ne) = 19.992439 u

Suppose, we think of fission of a

_{26}^{56} F e

nucleus into two equal fragments of

_{13}^{28} A l

. Is the fission energetically possible? Argue by working out Q of the process. Given m

(_{26}^{56} F e)

= 55.93494 u and m

(_{13}^{28} A l)

= 27.98191 u.

The fission properties of

_{94}^{239} P u

are very similar to those of

_{92}^{235} U

. The average energy released per fission is 180 MeV. How much energy, in MeV, is released if all the atoms in 1 kg of pure

_{94}^{239} P u

undergo fission?

Text solutionVerified

_{26}^{56} F e \to 2_{13}^{28} A l

M_{1} = 55.93494 u

is atomic mass of

F e

M_{2} = 27.98191 u

is atomic mass of

A l

Q

value is

(M_{1} - 2 M_{2}) \times 931.5 M e V

(55.93 - 2 \times 27.98) \times 931.5

\Rightarrow - 26.902 M e V

Q

is negative. Hence fission is not possible.
