Consider the following reaction between mercury(II) chioride and oxalate ion: What is the rate law for this reaction? 2HgCl2(aq)+C2O42(aq)2Cl(aq)+2CO2(g)+Hg2Cl2(s) The initial rate of this reaction was determined for several concentrations of HgCl2 and C2O42, and the following rate data were obtained for the rate of disappearance of C2O42 : Part B What is the value of the rate constant with proper units? Express your answer using two significant figures. What is the value of the rate constant with proper units? Express your answer using two significant figures. k= M2s1 Part C What is the reaction rate when the concentration of HgCl2 is 0.105M and that of C2O42 is 0.35M, if the temperature is the same as that used to obtain the data shown? Express your answer using two significant figures
