[-] [H.] , initial rate of reaction 1.75 M 0.767 M 16.0 M/s 7.77 M 0.767 M 71.0 M/ s 1.75 M 0.136 M 2.84 M/ s Use this information to write a rate law for this reaction, and calculate the value of the rate constant k. Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol. rate = k D k = ]

Use experimental data and the rate law to calculate a rate constant for each reaction 1, 2, 3, 4. How do the rate constants compare? Should they be the same or different? Discuss in your conclusions. Report the average value of your calculations. Be sure to include units in your rate constant. The rate law of the reaction is shown below: Rate = [Na2S2O3]-2
