For reaction aA rarr xP, when [A] = 2.2 ...

For reaction `aA rarr xP`, when `[A] = 2.2 mM`, the rate was found to be `2.4mM s^(-1)`. On reducing concentration of `A` to half, the rate changes to `0.6 mM s^(-1)`. The order of reaction with respect to `A` is

A

1.5

B

2

C

2.5

D

3

Text Solution

Verified by Experts

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