Conisder a reaction `aG+bH rarr` Products. When concentration of both the reactants `G` and `H` is doubled, the rate increases eight times. However, when the concentration of `G` is doubled, keeping the concentration of `H` fixed, the rate is doubled. The overall order of reaction is |

Answer» Correct Answer - D `aG+bHrarr`products The rate law is `Rate_(1)=k[G]^(x)[H]^(y)` Rate^(2)=k[2G]^(x)[2H]^(y)` Dividing rate by we get (Rate_(2))/(Rate_(1))=(8Rate_(1))/(Rate_(1))=(k[2g]^(x)[2H]^(y))/(k[G]^(x)[H]^(y))` `8=2^(x).2^(y)` `2^(3)2^(x+y)` :. Overall order is `3` . We need second information only if we asked about individual orders. |
