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

`1`

D

`2`

Text Solution

Verified by Experts

The correct Answer is:
B
Use: `R = k[B]^(n)`, `(1)/(4)R = k[2B]^(n)`, `4 = ((1)/(2))^(n)` ,
`4 = 2^(-n)`, `n = -2`.
