Q4 of 51 Page 427

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.
