Consider a radioactive disintegration according to the equation A rarrB rarrC . Deacy constant of A and B is same and equal to lamda . Number of nuclei of A, B and Care N_00, 0 respectively at t = 0. Find (a) Number of nuclei of B as function of time t. (b) Time t at which the activity of B is maximum and the value of maximum activity of B.

Answer»


ANSWER :(a) `N_(B) = lamdaN_(0) ("TE"^(-lamdat))` (b) `t = 1/lamda , R_(MAX) = (lamdaN_(0))/e`
