For the reaction `A rarr` Products, it is found that the rate of reaction increases by a factor of `6.25` when concentration of `A` increases by a factor of `2.5`. Calculate the order of reaction with respect to `A`. |

Answer» Correct Answer - 2 Rate `(r ) = k[A]^(n) = k[X]^(n)` …(i) `6.25 xx r k(2.5X)^(n)` …(ii) or `6.25 xx k xx(X)^(n) = k(2.5 xxX)^(n)` `rArr ((2.5)/(X))^(n) = 6.25 rArr (2.5)^(n) = (2.5)^(n)` `:. n = 2`Correct Answer - 2 Rate `(r ) = k[A]^(n) = k[X]^(n)` …(i) `6.25 xx r k(2.5X)^(n)` …(ii) or `6.25 xx k xx(X)^(n) = k(2.5 xxX)^(n)` `rArr ((2.5)/(X))^(n) = 6.25 rArr (2.5)^(n) = (2.5)^(n)` `:. n = 2` |
