Conisder a reaction aG+bH rarr Products....

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

A

`0`

B

`1`

C

`2`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
D
`r = k[G]^(m)[H]^(n)`
`8r = k[2G]^(m)[H]^(n)`
`:. m = 1, n = 2`,
`:.` Order `= m + n = 1 + 2 = 3`
