For the reaction: `aA + bB rarr cC+dD` Rate `= (dx)/(dt) = (-1)/(a)(d[A])/(dt) = (-1)/(b)(d[B])/(dt) = (1)/( c)(d[C])/(dt) = (1)/(d)(d[D])/(dt)` The rate of formation of `SO_(3)` in the following reaction `2SO_(2) + O_(2) rarr 2SO_(3)` is `100 g min^(-1)`. Hence the rate of disappearance of `O_(2)` isA. `2 g min^(-1)`B. `20 g min^(-1)`C. `200 g min^(-1)`D. `50 g min^(-1)` |

Answer» Correct Answer - B For the given reaction `(-d[O_(2)])/(dt) = (1)/(2)[d[SO_(3)])/(dt)` `(d[SO_(3)])/(dt) = 100 g min^(-1) = (100)/(80) mol min^(-1)` `:. (-d[O_(2)])/(dt) = (1)/(2)((100)/(80)) mol min^(-1)` `= (1)/(2) xx (100)/(80) xx 32 g min^(-1) = 20 g min^(-1)` |
