i didnt get it???? actually i didnt understand the QUestion statement!! pls if u could helppsee Kr has half life of 3 s.....there are two ways....one that u can set up an equation but thats more error prone so better off stick with the second method.........that after 1st 3 s Kr wd be 1/2.....after another 3 s it wud be 1/4th ......and after another 3 it wud be 1/8th whereas because of comparatively very big half life of Ba.....it wud decay be very small amount so after approx. 9 sec rattio will become 8
@OMG i Wanted to ask about an upper part of this question that why is fission energetically feasible......so ms was saying greater binding energy of products compared with reactants....bt how does it explain the energitcally feasible thing
