In the nuclear fusion reaction,
1H2 + 1H3 → 2He4 + n
given that the repulsive potential energy between the two nuclei is 7.7 x 10-14 J the temperature at which the gases must be heated to initiate the reaction is nearly [Boltzmann's constant, k = 1.38 x 10-23 J/K]
(a) 107 K
(b) 105 K
(c) 103 K
(d) 109 K
