Problem

Identify the reaction that is most likely to RELEASE energy spontaneously. a)

^{12}\mathrm{C}\; \rightarrow\; 3\,^{4}\mathrm{He}

^{4}\mathrm{He}+^{4}\mathrm{He}\; \rightarrow\; ^{8}\mathrm{Be}

^{2}\mathrm{H}+^{2}\mathrm{H}\; \rightarrow\; ^{3}\mathrm{He}+n

^{56}\mathrm{Fe}\; \rightarrow\; ^{28}\mathrm{Si}+^{28}\mathrm{Si}
