(D) The rate law for the reaction is given by: $Rate = k[AB]^n$. Using the data from the table: $2.75 \times 10^{-8} = k(0.20)^n$ --- $(i)$ $11.0 \times 10^{-8} = k(0.40)^n$ --- $(ii)$ Dividing equation $(ii)$ by equation $(i)$: $\frac{11.0 \times 10^{-8}}{2.75 \times 10^{-8}} = (\frac{0.40}{0.20})^n$ $4 = 2^n$ Since $4 = 2^2$,we have $2^2 = 2^n$. Therefore,$n = 2$. The reaction is of second order.
