what happens when the amount of fissionable material exceeds the critical mass? the chain reaction accelerates as more neutrons are generated with each round of reaction. the chain reaction is not sustained and eventually stops. the density of the reacting particles decreases, slowing the reaction. the amount of material needed to establish a new critical mass increases.

Answer

Brief Explanations:

In a nuclear fission chain - reaction, when the amount of fissionable material exceeds the critical mass, more neutrons are available to cause further fissions in each round of the reaction, accelerating the chain - reaction.

Answer:

The chain reaction accelerates as more neutrons are generated with each round of reaction.
