$\mathrm{A}\left(\mathrm{g}\right)+\mathrm{B}\left(\mathrm{g}\right)⟶\mathrm{C}\left(\mathrm{g}\right)$

The data below were obtained for the reaction between A and B. What is the rate law for this reaction?

Trial	$\begin{array}{c}[\mathrm{A}{]}_0\\ \left(\mathrm{mol}\cdot {\mathrm{L}}^{-1}\right)\end{array}$	$\begin{array}{c}[\mathrm{B}{]}_0\\ \left(\mathrm{mol}\cdot {\mathrm{L}}^{-1}\right)\end{array}$	Initial Rate of reaction  $(\mathrm{mol}. {\mathrm{L}}^{-1}.{\mathrm{s}}^{-1})$
1	0.10	0.10	$6.5\times {10}^{-5}$
2	0.20	0.10	$2.6\times {10}^{-4}$
3	0.10	0.20	$6.5\times {10}^{-5}$
