For a reaction 2SO_(2) + O_(2) ltimplies2SO_(3), rate of disappearance of O_(2) is 2xx10^(-4) mol L^(-1). The rate of appearance of SO_(3) is:

Answer»

`2xx10^(-4)mol L^(-1)s^(-1)`
`4 xx 10^(-4)mol L^(-1)s^(-1)`
`1 xx 10^(-1)mol L^(-1)s^(-1)`
`6 xx 10^(-4)mol L^(-1)s^(-1)`

SOLUTION :B) `2SO_(2)+O_(2) LTIMPLIES 2SO_(3)`
Rate of reaction:
`-1//2 (d[SO_(2)])/(dt) = (-d[O_(2)])/(dt) = 1/2(d[SO_(3)])/(dt)`
`2 xx 10^(-4) mol L^(-1)=1/2 (d[SO_(2)])/(dt)`
`(d[SO_(3)])/(dt) = 2 xx 2 xx 10^(-4) mol L^(-1)s^(-1)`
`=4xx10^(-4)mol L^(-1)s^(-1)`
