(C) The rate law for the reaction $A \rightarrow B$ is given by: $\text{Rate} = k[A]^{n}$,where $n$ is the order of the reaction. For the first condition: $2 \times 10^{-3} = k(0.05)^{n} \quad \dots(i)$ For the second condition: $1.6 \times 10^{-2} = k(0.1)^{n} \quad \dots(ii)$ Dividing equation $(ii)$ by equation $(i)$: $\frac{1.6 \times 10^{-2}}{2 \times 10^{-3}} = \frac{k(0.1)^{n}}{k(0.05)^{n}}$ $8 = (\frac{0.1}{0.05})^{n}$ $8 = (2)^{n}$ Since $8 = 2^{3}$,we have $2^{3} = 2^{n}$. Therefore,$n = 3$.

For a chemical reaction $A \rightarrow B$,the rate of the reaction is $2 \times 10^{-3} \ mol \ dm^{-3} \ s^{-1}$,when the initial concentration is $0.05 \ mol \ dm^{-3}$. The rate of the same reaction is $1.6 \times 10^{-2} \ mol \ dm^{-3} \ s^{-1}$ when the initial concentration is $0.1 \ mol \ dm^{-3}$. The order of the reaction is
