Problem: The rate of a certain reaction was studied at various temperatures. The table shows temperature (T) and rate constant (k) data collected during the experiments. Plot the data, and then answer the following questions. What is value of the activation energy, E a (kJ•mol -1), for this reaction? What is the value of the pre-exponential factor (sometimes frequency factor), A (s -1), for this reaction?
