The reaction 2 HgCl2(aq) + C2O42-(aq) 2 Cl-(aq) + 2 CO2(g) + Hg2Cl2(s) was studied at a certain temperature with the following results: Experiment [HgCl2(aq)] (M) [C2O42-(aq)] (M) Rate (M/s) 1 0.119 0.119 2.34e-05 2 0.119 0.238 9.37e-05 3 0.238 0.119 4.68e-05 4 0.238 0.238 0.000187 (b) What is the value of the rate constant? (c) What is the reaction rate when the concentration of HgCl2(aq) is 0.180 M and that of C2O42-(aq) is 0.281 M if the temperature is the same as that used to obtain the data shown above
