In the formation of sulphur trioxide by contact process,2SO_2 + O_2 to 2SO_3, the rate of reaction was measured as -(d[O_2])/(dt)= 2.5 xx 10^(-4)mol L^&(-1) s^(-1) Rate of reaction expressed in terms of SO_3 will be

Answer»

`-5.0 xx 10^(-4)` mol ` L^(-1)s^(-1)`
`-1.25 xx 10^(-4)`mol `L^(-1) s^(-1)`
`2.5 xx 10^(4)` mol `L^(-1) s^(-1)`
`5.00 xx 10^(-4)` mol `L^(-1) s^(-1)`

Solution :The RATE of reaction is same as expressed in TERMS of anyreactant or PRODUCT.
