Question

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)	C2O2−4(M)	Rate (M/s)
1	0.164	0.15	3.2×10−5
2	0.164	0.45	2.9×10−4
3	0.082	0.45	1.4×10−4
4	0.246	0.15	4.8×10−5

1. What is the reaction rate when the concentration of HgCl2 is 0.110 M and that of C2O2−4 is 0.60 M , if the temperature is the same as that used to obtain the data shown? in M/s.
