Select the law that correponds to data shown for the following reaction `A+B rarr` Products
`{:(Exp,[A],[B],"Initial rate",),(1,0.012,0.035,0.1,),(2,0.024,0.070,0.8,),(3,0.024,0.035,0.1,),(4,0.012,0.070,0.8,):}`

A

Rate `= k[B]^(3)`

B

Rate `= k[B]^(4)`

C

Rate `= k[A][B]^(3)`

D

Rate `= k[A]^(2)[B]^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
form experiments `(3)` and `(2)`, `[A]` is constant and `[B]` is doubled and rates becomes `8` times, so order w.r.t. `[B] = 3`.
form experiments `(1)` and `(3)`, `[B]` is constant and `[A]` is doubled, but rate does not change, so order w.r.t `[A] = 0`. Thus,
rate `= k[B]^(3)`
