Question

what effect does supercritical mass have on a nuclear reaction?
the reaction rate increases.
the reaction produces less energy.
the reaction involves increased fusion.
the reaction produces fewer neutrons.

Explanation:

Super - critical mass in a nuclear reaction means there are more than enough neutrons to sustain and accelerate the chain reaction, thus increasing the reaction rate. Nuclear fission is the main process in such cases, not fusion. More neutrons are produced, and more energy is released.

Answer:

The reaction rate increases.
