At the point of intersection of the two curves shown, the conc. of `B` is given by ……… for, `A rarr nB`:

A

`(nA_(0))/2`

B

`A_(0)/(n-1)`

C

`(nA_(0))/(n+1)`

D

`((n-1)/(n+1))A_(0)`

Text Solution

Verified by Experts

The correct Answer is:
c
From fig.,
`[A]_("left")=[B]_("formed")=nxx[A]_("decayed")`
`:. [A_(0)]e^(-lambdat)=nxxA_(0)[1-e^(-lambdat)]`
`:. e^(-lambdat)=n/(n+1)`
`:. [B]_("formed")=nxxA_(0)xx[1-n/(n+1)]`
`=(nA_(0))/(n+1)`
