The rate of the following reaction in aqueous solution is monitored by measuring the number of moles of Hg2Cl2 formed per litre per minute. The data obtained are listed in the table.
2 HgCl2(aq) + C2O42–(aq) → 2 Cl–(aq) + 2 CO2(g) + Hg2Cl2(s)
Experiment | [HgCl2] (M) | [C2O42–] (M) | Rate (mol L–1 min–1) |
1 | 0.106 | 0.150 | 1.78×10–5 |
2 | 0.053 | 0.300 | 3.56×10–5 |
3 | 0.053 | 0.150 | 8.90×10–6 |
Determine the order of reaction with respect to HgCl2, with respect to C2O42– and overall.
| Order with respect to HgCl2: | |
| Order with respect to C2O42–: | |
| Overall: |
