Rate Law from Initial Rates $($B$)$

$2Cl{O}_2(aq)+2O{H}^{-}(aq)longrightarrowCl{O}_3^{-}(aq)+Cl{O}_2^{-}(aq)+H_{2}O(I)$

The above reaction was studied $($at a particular temperature$)$ and the following data $($for rate $=-d\frac{Cl{O}_2}{d}t)$ were obtained:

$\backslash$table$[[[Cl{O}_2{]}_0,[O{H}^{-}{]}_0,$Initial Rate$],[(mo\frac{l}{L}),(mo\frac{l}{L}),(mol{L}^{-1}{s}^{-1})$
