The rate law equation for a reaction A r...

The rate law equation for a reaction `A rarr B` is ,
`r = k[A]^(0)`
If the initial concentration is 'a' mol `"dm"^(-3)`, the half of the reaction is

A

`(k)/(a)`

B

`(a)/(k)`

C

`(2a)/(k)`

D

`(a)/(2k)`

Text Solution

Verified by Experts

The correct Answer is:
D
According to the rate equation given the reaction is of zero order .
For a zero order reaction, `t_(1//2)prop a`
or `t_(1//2)=(a)/(2k)`
