Problem

Three α-particles (4 ⁣He^4\!\mathrm{He} nuclei) combine to form one 12 ⁣C^{12}\!\mathrm{C} nucleus. The average binding energy per nucleon is 7.1 MeV for 4 ⁣He^4\!\mathrm{He} and 7.6 MeV for 12 ⁣C^{12}\!\mathrm{C}. Determine whether this reaction is exothermic or endothermic, supporting your answer with a suitable calculation.
