Exercise 50. The easiest fusion reaction to initiate is
21H + 31H → 42He + 10n
Calculate the energy released per 42He nucleus produced and per mole of 42He produced. The atomic masses are 21H, 2.01410 u; 31H, 3.01605 u; and 42He, 4.00260 u. The masses of the electron and neutron are 5.4858 X 10-4 u and 1.00866 u, respectively.
Using the kinetic molecular theory, calculate the root mean square velocity and the average kinetic energy of 21H nuclei at a temperature of 4 X 10 7 K. (See Exercise 50 for the appropriate mass values.)
