For the reaction below, several initial rate experiments are performed and the data are

summarized in the table.

$2HgC{l}_2+C_2{O}_4^{2-}2C{l}^{-}+2C{O}_2+H{g}_{2}C{l}_2$

a$.$ Determine the reaction order with respect to each reactant

b$.$ Determine the rate constant

c$.$ If $[HgC{l}_2]=0\mathrm{.}65$ and $[C_2{O}_4^{2-}]=0\mathrm{.}45,$ determine the rate.
