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

Answer»

`2xx10^(4) "mol L"^(-1)s^(-1)`
`4XX10^(-4)"mol L"^(-1)s^(-1)`
`1xx10^(-4) "mol L"^(-1)s^(-1)`
`6XX10^(-4) "mol L"^(-1)s^(-1)`

Solution :`(Delta[O_(2)])/(Deltaf)=2xx10^(-4)`
`([SO_(3)])/(Deltat)=2(Delta[O_(2)])/(Deltat)`
`=2xx2xx10^(-4)`
`=4xx10^(-4) " mol "1^(-1) s^(-1)`
