Determining Activation Energy An AP Chemistry In-Class Activity 1) The following data was collected for two diffefrent reactions. a) Determine the Activation Energy for each reaction by: plotting ln(k) vs (1/T), finding the slope and multiplying the slope by R (8.314 J/ °K mol) E a-exp 1 = 79.2 kJ/mol E a-exp 2 = 138.8 kJ/mol b) Determine each reaction’s Activation Energy by using Arrhenius Equation . E a-exp 1 = 79.3 kJ/mol E a-exp 2 = 144 kJ/mol c) Using the graphs tha you created, calculate A , the Arrhenius Constant
