Without performing complex calculations,determine the order of a reaction that has the following initial rates for the specified starting concentration: $$\begin{array} { l | l }
{ [ \mathrm { A } ] \left( \mathrm { mol } \mathrm { L } ^ { - 1 } \right) } & \text { Initial Rate } \left( \mathrm { mol } \mathrm { L }^{ - 1} \mathrm {~s} ^ { - 1 } \right) \
\hline 0.20 & 0.0050 \
0.40 & 0.020 \
0.80 & 0.080
\end{array}$$
