Conisder a reaction `A rarr B + C` . The initial concentration of `A` was reduced form `2 M `to `1 M` in `1 h` and form `1M` to `0.25 M` in `2h`, the order of the reaction is

A

`1`

B

`0`

C

`2`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
A

(a) Half life of the given reaction is independent of initial concentration, hence it is a first order reaction.
`[t_(1//2)prop(1)/(a^(n-1))]`
