The Reaction Energy Q is defined as; if initial particles A and B interact to produce final particles C and D;

$Q=[M_A+M_B-M_C-M_D]脳931.5MeV/u$

As given;

Atomic mass of ${}_1{}^{1}HisM\left({}_1{}^{1}H\right)=1.007825u$.

Atomic mass of ${}_1{}^{2}HisM\left({}_1{}^{2}H\right)=2.014102u$.

Atomic mass of ${}_1{}^{3}HisM\left({}_1{}^{3}H\right)=3.016029u$.

Atomic mass of ${}_2{}^{4}HisM\left({}_2{}^{4}H\right)=4.002603u$.

The fusion reaction is;

${}_2{}^{3}He+{}_1{}^{2}H鈫�{}_2{}^{4}He+{}_1{}^{1}H$

The number of electrons in this equation is equal on both sides; therefore, using the atomic masses of these elements in reaction energy, since the mass of the electron cancels out, now plugging the value into the equation;

$$\begin{gathered} Q=[3.016029u+2.014102u-4.002603u+1.007825u]脳931.5MeV/u \\ =[0.019803u]脳931.5MeV/u \\ Q=18.446MeV \end{gathered}$$

The reaction is exoergic because the reaction energy is negative.

Hence, the energy released in the fusion reaction is Q=18.446MeV.
