(a(i))[2]
State what nuclear binding energy means.
(a(ii))[2]
On Fig. 8.1, draw a line to show how the binding energy per nucleon $E$ of a nucleus varies with nucleon number $A$.
(b)
In one nuclear process, deuterium $^{2}_{1}\text{H}$ takes part in the reaction $^{2}_{1}\text{H} + {}^{2}_{1}\text{H} \rightarrow {}^{3}_{2}\text{He} + {}^{1}_{0}\text{n}$.
(b(i))[1]
State the name of this kind of nuclear process.
(b(ii))[2]
Explain, with reference to your line in (a)(ii), why this reaction leads to the release of energy.
(c)[5]
Table 8.1 gives the masses of the particles in the reaction in (b). Calculate the energy released when $1.00\,\text{mol}$ of deuterium undergoes the reaction.
