Multiple Choice

Why might the following nuclear reaction not be very good for energy production in a fission reactor? U → Ba + Kr + 1 neutron

A) The material only produces one neutron so the chain reaction will not be very efficient.
B) The products are too large.
C) There are too many products produced.
D) The mass of the byproducts is too high and therefore the energy released will not be high enough.
E) Interatomic attraction between the products will impede the efficient separation of the atoms from the unstable nuclei.
