For the reaction `A + B` products, it is observed that:
(1) on doubling the initial concentration of `A` only, the rate of reaction is also doubled and
(2) on doubling te initial concentration of both `A` and `B`, there is a charge by a factor of `8` in the rate of the reaction.
The rate of this reaction is given by

A

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

B

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

C

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

D

Rate = `k[A][B]`

Text Solution

Verified by Experts

The correct Answer is:
B
When concentration A is doubled rate is doubled Hence order with respect to A is one .
When concentrations of both A and B are doubled , rate increases by 8 times hence total order is 3 .
:. Rate = `k[A]^(1)[B]^(2)`
Order = `1+2=3`
