The table shows temperature (7) and rate constant (k) data collected during the experiments. Plot the data to answer the questions. E, = Textbook E-ven What is the value of the activation energy, E,. for this reaction? A = KJ molt What is the value of the pre-exponential factor (sometimes called the frequency factor), A. for this reaction?
