For a nuclear reactor, 48 kJ of energy is produced per minute. If the energy released per fission is 3.2 × 10-11 J, then the number of fission which would be taking place in a reactor per second is
Given:
Total energy released per minute = 48 kJ
= 48 × 103 J
Energy produced per second
= 0.8 × 103 J
Energy release per fission = 3.2 x 10-11 J
Solution
= 2.5x1013
Therefore number of fission per second is 2.5x1013.
So the correct answer is D.
