Two consecutive irreversible fierst order reactions can be represented by
`Aoverset(k_(1))(rarr)Boverset(k_(2))(rarr)C`
The rate equation for A is readily interated to obtain
`[A]_(t)=[A]_(0).e^(-k_(1^(t)))` , and `[B]_(t)=(k_(1)[A]_(0))/(k_(2)-k_(1))[e^(-k_(1)^(t))-e^(-k_(2)^(t))]`
At what time will B be present in maximum concentration ?

A

`(K_(1))/(K_(2)-K_(1))`

B

`(1)/(k_(1)-k_(2))` In `k_(1)/(k_(2))`

C

`(1)/(k_(2)-k_(1))` In `k_(1)/(k_(2))`

D

none of these
