Consider the following reaction between mercury(II) chloride and oxalate ion:
2HgCl2(aq)+C2O2/4-(aq)→2Cl−(aq)+2CO2(g)+Hg2Cl2(s)
The initial rate of this reaction was determined for several concentrations of HgCl2 and C2O2/4-, and the following rate data were obtained for the rate of disappearance of C2O2/4-
| Experiment | HgCl2(M)HgCl2(M) | C2O2−4(M)C2O42−(M) | Rate (M/s)(M/s) |
| 1 | 0.164 | 0.15 | 3.2×10−53.2×10^−5 |
| 2 | 0.164 | 0.45 | 2.9×10−42.9×10^−4 |
| 3 | 0.082 | 0.45 | 1.4×10−41.4×10^−4 |
