1. As mentioned in Section (1.2), the p.p fusion reaction is the source for mech of the energy produced by the sun, as represented by Equation (1.1): 4i++24He2++2+2++2vr,Q=24.69MeV Under the conditions found in a star's interior, the reaction involves ionized species as shown. However, isotope masses are usually tabulated for neutral atoms, not ions. Adding four electrons to each side of the reaction, we obtain 41H24He+2+2++2ve+2e Compute the Q for the latter reaction. Is it the same as the value given above? 2. The p-p reaction actually comprises several steps. The first step is the fusion of hydrogen into deuterium: H-Hfusion:1H+1H2D+++Vc The second step is the fusion of deuterium and hydrogen to form helium-3; D-H fusion: 12D+IIH23He+ Most commonly, the final step is the fusion of two He-3 nuclei (although other reactions are possible): He-3fusion:3He+3He+4He+7H+7H (a) Compute the Q for each step of the PP fusion chain. (b) Combine the H-H fusion, D-H fusion, and He-3 fusion equations to obtain a balanced equation for the overall p-p fusion reaction. Is the resulting fusion reaction the same as Equation (t.i)? I. 10. PROBLFMS 19 (c) Sum the Q-values you cornputed for part (a). Does the result agree with Equation (1.1)
