A follows first order reaction.
`(A) rarr Product`
The concentration of `A` changes form `0.1 M` to `0.025 M` in `40 min`. Find the rate of reaction of `A` when the concentration of `A` is `0.01 M`.

A

(a) `1.73xx10^(-4) M//min`

B

(b) `3.47xx10^(-5) M//min`

C

(c ) `3.47xx10^(-4) M//min`

D

(d) `1.73xx10^(-5) M//min`

Text Solution

Verified by Experts

The correct Answer is:
c
`K=2.303/40"log"0.1/0.025=0.0347`
Rate`=Kxx[X]=0.0347xx0.01`
`=3.47xx10^(-4) M min^(-1)`
