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

Options

A. Rate = `K[A][B]^2`
B. Rate = `K[A]^2[B]^2`
C. Rate = k [A][B]
D. Rate = `K[A]^2[B]`

Answer

A
