For a chemical reaction `A rarr B`, it is found that the rate of reaction doubles when the concentration of `A` is increased `4` times. What is the order of reaction ? Suggest the rate law also.

A

`2`

B

`1`

C

`1//2`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
C
`r_(1) = k[A]^(n)`
`r_(2) = 2r_(1) = k[4A]^(n)`
`(2r_(1))/(r_(1)) = (4)^(n)`
`(2)^(1) = (2)^(2n)`
`n = (1)/(2)`
