A radioactive nucleus X converts into nucleus Y by emitting `B^+`. If atomic masses of X and Y are `M_X` and `M_Y` then Q value of reaction will be :-

`Q=M_x C^2`

`Q = (M_X - M_Y - M_e) C^2`

`Q=(M_X - M_Y)C^2`

`Q = (M_X-M_Y-2m_e)C^2`

The radioactive nucleus of an element X decays to a stable nucleus of element Y.A graph of the rate of romation of Y against time would look like:

A radioactive nucleus X decays to a nucleus Y with a decay constant lambda_X=0.1s^-1 , Y further decays to a stable nucleus Z with a decay constant lambda_Y=1//30s^-1 . Initially, there are only X nuclei and their number is N _0=10^20 . Set up the rate equations for the populations of X, Y and Z. The population of Y nucleus as a function of time is given by N_Y(t)={N _0lambda_X//(lambda_X-lambda_Y)}[exp(-lambda_Yt)-exp(-lambda_Xt)] . Find the time at which N_Y is maximum and determine the population X and Z at that instant.
