(B) The rate law for the reaction is given by: $\text{Rate} = k[A]^n$,where $n$ is the order of reaction.For the first condition: $2.4 = k(2.2)^n$ ... $(i)$For the second condition,$[A] = 2.2/2 = 1.1 \, mM$ and $\text{Rate} = 0.6 \, mM \, s^{-1}$:$0.6 = k(1.1)^n$ ... $(ii)$Dividing equation $(i)$ by equation $(ii)$:$\frac{2.4}{0.6} = \frac{k(2.2)^n}{k(1.1)^n}$$4 = (2)^n$$2^2 = 2^n$Therefore,$n = 2$.The order of reaction with respect to $A$ is $2$.
