The chemical reaction between mercuric chloride and potasisum oxalate proceeds as under:  `2HgCl_(2) + K_(2)C_(2)O_(4) rarr KCl + 2CO_(2) + Hg_(2)Cl_(2)`  The mass of `Hg_(2)Cl_(2)` precipitated form different solutions in a given time at `100^(@)C` was as follows:  `|{:("Experiment number",HgCl_(2) (mol L^(-1)),K_(2)C_(2)O_(4) (mol L^(-1)),"Time (min)",Hg_(2)Cl_(2) "precipitated (mole)"),(1,0.0836,0.404,65,0.0068),(2,0.0836,0.202,120,0.0031),(3,0.0418,0.404,60,0.0032):}|`   form the data calculate order of the reaction.
