`U-235` can decay by many ways , let us here consider only two ways, `A` and `B`. In decay of `U-235` by means of `A`, the energy released per fission is `210 MeV` while in `B` it is `186 MeV`. Then , the uranium `235` sample is more likely to decay by .

Options

A. scheme `A`
B. scheme `B`
C. equally likely for both schemes
D. it depends on half-life of schemes A and `B`

Answer

a

Explanation

Since scheme A release more energy than scheme B, scheme A is more likely to occur. This is because the more energy released , the more stable the daughter nuclues is , A heavy nucleus undergoes fission such that its producets will be more stable than the parent nucleus.
