The Q value of a nuclear reaction, A + b → C + d, is defined by
Q = [mₐ + mᵦ]−[m + m]
where, the masses refer to the respective nuclei. Determine from the given data the Q-value of the following reactions and state whether the reactions are exothermic or endothermic.
(i) ¹₁H + ¹₃H → ²₁H + ²₁H
(ii) ¹²₆C + ¹²₆C → ²⁰₁₀Ne + ⁴₂He
Atomic masses are given to be
m(²₁H)= 2.014102 u
m(³₁H)= 3.016049 u
m(¹²₆C)= 12.000000 u
m(²⁰₁₀Ne)= 19.992439 u
