Select the law that corresponds 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]^(3)[B]`

Text Solution

Verified by Experts

The correct Answer is:
A
It is seen that, in experiments (3) and (2), [A] is constant and [B] is doubled and rates becomes 8 times, so order with respect to [B] = 3. In experiments (1) and (3), [B] is constant and [A] is doubled, but rate does not change, so order with respect to [A] = 0 Thus, rate = `k[B]^(3)`
