O KINETICS AND EQUILIBRIUM Deducing a rate law from initial reaction rate data Some measurements of the initial rate of a certain reaction are given in the table below. H, I, initial rate of reaction 0.735 M 0.260 M 78.0M/s 0.735 M 0.341 M 102. M/s 0.354 M 0.260 M 37.6M/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. Do rate = k| x10 k = Explanation Check © 2021 McGraw-Hill Educat II
