$aA\to xP$ Rate of reaction $=[A{]}^a$ Order of reaction $=a$ $[A{]}_1=2.2\mathrm{mM},r_1=2.4\mathrm{mM}{\mathrm{s}}^{-1}$ $[A{]}_2=\frac{2.2}{2}\mathrm{mM},r_2=0.6$ or $\frac{2.4}{4}\mathrm{mM}{\mathrm{s}}^{-1}$ On reducing the concentration of $A$ to half, the rate of reaction is decreased by four times. $\therefore$ Rate of reaction $\propto [A{]}^2$ $\Rightarrow$ Order of reaction $=2$
