For a reaction $\displaystyle \mathrm{A} \rightarrow 2 \mathrm{~B}+\mathrm{C}$ the half lives are $\displaystyle 100$ s and $\displaystyle 50$ s when the concentration of reactant A is $\displaystyle 0.5$ and $\displaystyle 1.0 \mathrm{~mol} \mathrm{~L}^{-1}$ respectively. The order of the reaction is \_\_\_\_. (Nearest Integer)
