`2SO_(2)(g)+O_(2)(g) hArr 2SO_(3)(g)`
The rate of reaction is expressed as
`-(d(O_2))/(dt) = 2.5 xx 10^(-4) mol L^(-1) s^(-1)`
The rate of disappearance of `(SO_(2))` will be-

A

`5.0xx10^(-4) "mol " L^(-1)s^(-1)`

B

`-2.25xx10^(-4)"mol "L^(-1)s^(-1)`

C

`3.75xx10^(-4)"mol "L^(-1)s^(-1)`

D

`50.0xx10^(-4)"mol "L^(-1)s^(-1)`

Text Solution
