The above is a plot of binding energy per nucleon EbE_b, against the nuclear mass M;A,B,C,D,E,FM ; A, B, C, D, E, F correspond to different nuclei. Consider four reactions: (i) A+B→C+εA+B \rightarrow C+\varepsilon (ii) C→A+B+ε\mathrm{C} \rightarrow \mathrm{A}+\mathrm{B}+\varepsilon (iii) D+E→F+ε\mathrm{D}+\mathrm{E} \rightarrow \mathrm{F}+\varepsilon and (iv) F→D+E+εF \rightarrow D+E+\varepsilon where ε\varepsilon is the energy released? In which reactions is ε\varepsilon positive? The above is a plot of binding energy per nucleon E_b , against the nuclear mass M ; A, B, C, D, E, F correspond to
