Why is such a high temperature required

Reference no: EM131026710

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

4 ₁¹H → ₂⁴He + 2 ₁⁰e

which requires a temperature of to .

(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?
