Consider the following reaction:2 HgCl2(aq) + C2O42-(aq) 2 Cl-(aq) + 2 CO2(g) + Hg2Cl2(s) (b) If the rate constant for this reaction at a certain temperature is 0.0158, what is the reaction rate when [HgCl2(aq)] = 0.186 M and [C2O42-(aq)] = 0.228 M?Rate = ____ M/s.(c) What is the reaction rate when the concentration of HgCl2(aq) is doubled, to 0.372 M while the concentration of C2O42-(aq) is 0.228 M?Rate = ____ M/s

To calculate rate of reaction , we would first write rate law for the given reaction . From the given reaction equation , rate law can be written as : rate = k [ HgCl2][C2O42-] where, k = rate constant = 0.0158 a ) Now plug the values of concentrations of both compounds and value of k , we have rate = 0.0158 × ( 0.186 )2 × (0.228 ) rate = 1.25 × 10-4 M/s b.) Now it is given that concentration of HgCl2 is doubled . So we have : rate = 0.0158 × ( 0.372 )2 × ( 0.228 ) rate = 4.98 × 10-4 M/s
