Calculate the Q-values of the fusion reaction
`He^4+He^4 = Be^8`
In such a fusion energetically favourable? Atomic mass of `Be^8` is 8.0053u and that of `He^4`is 4.0026 u.

Text Solution

Verified by Experts

The correct Answer is:
A, C

Required value
`=(2 xx 4.0026 - 8.0053)uC^2`
`=0.0001 xx 931 (MeV)/(C^2) xx C^2`
`=0.0001 xx 931 xx 10^6 eV`
`=93.1 KeV` .
