In the formation of sulphur trioxide by the contact process, `2SO_(2)+O_(2) hArr 2SO_(3)`, the rate of reaction was measured as `(d[O_(2)])/(d t) = 3.0 xx 10^(-4) "mol" L^(-1)s^(-1)`. The rate of reaction expressed in terms of `SO_(3)` will beA. `3.0 xx 10^(-4) mol L^(-1) s^(-1)`B. `6.0 xx 10^(-4) mol L^(-1) s^(-1)`C. `1.5 xx 10^(-4) mol L^(-1) s^(-1)`D. `4.5 xx 10^(-4) mol L^(-1) s^(-1)` |

Answer» Correct Answer - B `-(d[O_(2)])/(d t) = +(1)/(2)(d[SO_(3)])/(d t)` `3 xx 10^(-4) = (1)/(2) (d[SO_(3)])/(d t)` `(d[SO_(3)])/(d t) = 6 xx 10^(-4) M//sec`. |
