For a hypothetical reaction `Ararr B`, the rate constain is `0.25 s^(-1)`. If the concentration of `A` is reduced to half, then the value of rate constant is

A

`0.25 s^(-1)`

B

`0.30 s^(-1)`

C

`0.075 s^(-1)`

D

`2.25 s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Rate constant for first order reaction is independent of initial concentration. Thus,
`k=0.25 s^(-1)`
