rate constant and rate of reaction

The rate of the following reaction in aqueous solution is monitored by measuring the number of moles of Hg2Cl2 that precipitate per liter per minute. The data obtained are listed in the table.
2HgCl2 + (C2O4^2-) ----> (2Cl^-) + 2CO2 (g) + Hg2Cl2 (s)
Experiment [HgCl2],M ([C2O4]^2-),M Initial rate,mol L^-1min-1
1 0.105 0.15 1.8 x 10^-5
2 0.105 0.30 7.1 x 10^-5
3 0.052 0.30 3.5 x 10^-5
4 0.052 0.15 8.9 x 10^-6

1.) Determine the order of the reaction with respect to HgCl2, with respect to (C2O4^2-) and overall:

HgCl2
(a)first
(b)second
(c)third

(C2O4^2-)
(a)first
(b)second
(c)third

overall order of reaction:
(a)first
(b)second
(c)third

2.)What is the value of the rate constant k? (in M^-2 min^-1)
3.)What would be the initial rate of reaction if [HgCl2] = 0.020 M and [C2O4^2-] = 0.22 M? (in M/min)

Solution Summary

It detemines the rate constant, rate of reaction, and the order of the reaction. The solution is detailed and has a '5/5' rating.
