1. The following set of data was obtained by the method of initial rates for the reaction:
2 HgCl2(aq) + C2O42-(aq) --> 2Cl-(aq) + 2 CO2 (g) + Hg2Cl2(s)
HgCl2 (M): C2O42- (M): Rate (M/s)
0.10 0.10 1.3x 10-7
0.10 0.20 5.2 x 10-7
0.20 0.20 1.0 x 10-6
(a) What is teh rate law for the reaction(b) what is the value of the rate constant
