Chapter , Problem 63E

(choose chapter or problem)

A portion of the Sun’s energy comes from the reaction

\(4_{1}^{1} H \rightarrow{ }_{2}^{4} H e+2_{1}^{0} e\)

which requires a temperature of \(10^{6}\) to \(10^{7}\) K. (a) Use the mass of the helium-4 nucleus given in Table 21.7 to determine how much energy is released when the reaction is run with 1 mol of hydrogen atoms. (b) Why is such a high temperature required?
