Solution: Consider the following reaction between mercury(II) chloride and oxalate ion: pandoc: Error at "source" (line 1, column 64): unexpected "-" expecting "{" or "" 2{ m HgCl_2}(aq) + { m C_2O_4^{2-}}(

Problem
Consider the following reaction between mercury(II) chloride and oxalate ion:
pandoc: Error at "source" (line 1, column 64): unexpected "-" expecting "{" or "" 2{ m HgCl_2}(aq) + { m C_2O_4^{2-}}(aq) ightarrow 2{ m Cl^-}(aq) + 2{ m CO_2}(g) + { m Hg_2Cl_2}(s)
The initial rate of this reaction was determined for several concentrations of { m HgCl_2} and { m C_2O_4^{2-}}, and the following rate data were obtained for the rate of disappearance of { m C_2O_4^{2-}}:

Experiment { m HgCl_2};{ m (M)} { m C_2O_4^{2-}};{ m (M)} Rate { m (M/s)}
1 0.164 0.15 3.2 imes 10^{ - 5}
2 0.164 0.45 2.9 imes 10^{ - 4}
3 0.082 0.45 1.4 imes 10^{ - 4}
4 0.246 0.15 4.8 imes 10^{ - 5}

What is the reaction rate when the concentration of HgCl2 is 0.130 M and that of C2O42- is 0.45 M , if the temperature is the same as that used to obtain the data shown?
