Question

Calculate the total energy released during a fission reaction .
``
The resulting fission fragements are unstable hence, decay into stable and products `` and `` by sucessive emission of `beta`-particles . Take mass of neutron = 1.0087 amu , mass of ``=236.0526 amu, mass of ``=97.9054 amu and mass of ``=135.9170 amu.
A. 198 MeV
B. 220 MeV
C. 185 MeV
D. 230 MeV

Answer 1

Correct Answer - A
`_(0)^(1)n + _(92)^(235)U to _(42)^(98)Mo + _(54)^(136)Xe + 2_(0)^(1)n`
`(1.0087 + 235.0439 ) = ( 97.9054 + 135.917 + 2.0174)`
`Delta`m = 0.2128
`therefore` Total energy released during a fission reaction
`= 0.2128 xx 931` MeV = 198 MeV
