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 `1dm^(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`
