For a reation: `A rarr` Product,
rate law is `-(d[A])/(dt)=K[A]_(0)`.
The concentration of `A` left after time `t` when `t=1/K` is:

A

`[A]_0/e`

B

`[A]_0xxe`

C

`[A]_0/e^2`

D

`1/[A]_0`

Text Solution

Verified by Experts

For 1 order reaction :
`[A]_t=[A]_0xxe^(-kt), "But" t = 1/k`
`:. [A]_t=[A]_0e^(k xx 1//k)=[A]_0/e`
