Question

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. H2 initial rate of reaction 53.0 m/s 1.28 M 1.28 M 0.130 M L2] 2.30 M 0.284 M 2.30 M 6.54 M/s 5.38 MIS 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 = * X 5
please help me solve this, i only get ONE try so please please make sure the answer is right, thanks!!
