Consder the follswing reaction between mercury(ti) chloride and oxalate ion. \[ 2 \mathrm{HgCO}_{2}(a q)+\mathrm{C}_{2} \mathrm{O}_{4}^{2} \text { (aq) } \rightarrow 2 \mathrm{O} \text { (ap) }+2 \mathrm{CO}_{2}(9)+\mathrm{H}_{2} \mathrm{C}_{2}(\mathrm{~s}) \] The intial rate of this reaction was determined for several concentrations of \( \mathrm{HgO}_{2} \) and \( \mathrm{C}_{2} \mathrm{O}_{4}^{2} \), and the folowing rate data were cotained for the rate of dicapetarance of \( \mathrm{C}_{2} \mathrm{O}_{4}{ }^{2} \). (a) What is the rate iaw for this reacion? \( \mathrm{KHSS}^{2} \mathrm{HCjO}_{4} \mathrm{~T}^{2 / 42} \) kHgO \( \mathrm{H}_{2}\left(\mathrm{C}_{2} \mathrm{O}_{4}{ }^{-2}\right\}^{2} \) (b) What is the valoe of the nate contara? \[ M^{2} \mathrm{M}^{1} \text {. } \] \( \mathrm{N} / \mathrm{s} \)
