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.

The correct answer is "The reaction rate increases."

Explanation:

Supercritical mass is the mass of nuclear reactor fuel which is more than sufficient to sustain a nuclear chain reaction. At critical mass there is a stable or slow nuclear reaction. However, at supercritical mass such as in a nuclear bomb there is exponentially increasing number of nuclear fission reactions occurring in quick succession.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
