The reaction, `2SO_(2(g)) + O_(2(g))hArr2SO_(3(g))` is carried out in a 1 `dm^(3)` and 2 `dm^(3)`vessel separately. The ratio of the reaction velocity will be

Options

A. `1:8`
B. `1:4`
C. `4:1 `
D. `8:1`

Answer

D

Explanation

`2SO_(2(g))+O_(2(g))hArr2SO_(3(g))`
For `1 dm^3 " " R =k [SO_2]^2 [O_2]`
`R=K[1/1]^2[1/1]=1`
For `2dm^(3) R = K [1/2]^2[1/2]=1/8`
So, the ratio is 8 : 1.
