Problem Details

The following set of data was obtained by the method of initial rates for the reaction:

2 HgCl2(aq) + C2O42-(aq) → 2 Cl-(aq) + 2 CO2(g) + Hg2Cl2(s)

What is the rate law for the reaction?

Experiment     Initial [HgCl2], M      Initial [C2O42-], M               Rate, M/s
1                            0.10                            0.10                            1.3 x 10-7
2                            0.10                            0.20                            5.2 x 10-7
3                            0.20                            0.20                            1.0 x 10-6

a. Rate = k[C2O42-]

b. Rate = k[HgCl2]2[C2O42-]

c. Rate = k[HgCl2]2[C2O42-]2

d. Rate = k[HgCl2][C2O42-]2

e. Rate = k[HgCl2]
