For the reaction `(A)+(B) rarr (C)+(D)`, doubling the concentration of both the reactants increases the reaction rate by 8 times and doubling the concentration of only `B` just dobles the reaction rate. The rate law is given as

Options

A. `r=k^(*)[A]^(1 / 2 cdot)[B]^(t / 2)`
B. r=k[A][B]^(2)
C. `r=k[A]^(2)[B]`
D. `r=k[A][B]`

Answer

C
