For the reaction , `2SO_(2) +O_(2) hArr 2SO_(3)`,
the rate of disappearance of `O_(2)` is `2xx10^(-4)"mol L"^(-1)s^(-1)`. The rate of appearance of `SO_(3)` is

Options

A. `2 xx 10^(-4) "mol L"^(-1)s^(-1)`
B. `6 xx 10^(-4) "mol L"^(-1)s^(-1)`
C. `1 xx 10^(-4) "mol L"^(-1)s^(-1)`
D. `6 xx 10^(-4) "mol L"^(-1)s^(-1)`

Answer

B

Explanation

`2SO_2+O_2 hArr 2SO_3`
Rate of reaaction
`=1/2(d[SO_2])/(dt)=(d[O_2])/(dt)=1/2(d[SO_3])/(dt)`
`2xx10^(-4)=1/2(d[SO_3])/(dt)`
`(d[SO_3])/(dt)=2xx2xx10^(-4)=4xx10^(-4)" mol L"^(-1)s^(-1)`
