The energy released per nuclear reaction is the resultant binding energy. Binding energy of $\left({}_1^2\mathrm{H}+{}_1^3\mathrm{H}\right)=a+b$ Binding energy of ${}_2^4\mathrm{He}=c$ In a nuclear reaction the resultant nucleus is more stable than the reactants. Hence, binding energy of ${}_2^4\mathrm{He}$ will be more than that of $\left({}_1^2\mathrm{H}+{}_1^3\mathrm{H}\right)$ Thus, energy released per nucleon $\begin{array}{rl}& =\text{ resultant binding energy }\\ & =c-(a+b)=c-a-b\end{array}$
