The rate of reaction between two A and B...

The rate of reaction between two `A` and `B` decreases by factor `4` if the concentration of reactant `B` is doubled. The order of this reaction with respect to `B` is

A

`-1`

B

`-2`

C

`2`

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
B
`r = K[A]^(m)[B]^(n)`
`(1)/(4) = 2^(n)`
`n = - 2`.
