For the decompoistion of `HI` at `1000 K(2HI rarr H_(2)+I_(2))`, following data were obtained:
`|{:([HI] (M),"Rate of decomposition of HI" (mol L^(-1) s^(-1))),(0.1,2.75 xx 10^(-8)),(0.2,11 xx 10^(-8)),(0.3,24.75 xx 10^(-8)):}|`
The order of reaction is

A

1

B

2

C

0

D

`1.5`

Text Solution

Verified by Experts

Rate `k=[HI]^(n)`
`11xx10^(-8)=k[0.2]^(n)" "....(i)`
`2.75xx10^(8)=k[0.1]^(n)" "....(ii)`
Divinding eq. (i) by eq. (ii),
`4=2^(n),n=2`
