Transcribed Image Text:2. For the reaction we studied: 21- + S20g?- –> I2 + 2 SO42- AETX AHrxn = -322 kJ/mol %3D A. Use this value and your experimental activation energy value to draw an energy profile for the reaction with the energies appropriately scaled on the vertical axis. B. Label AErxn (AHrxn) and Ea on the graph. C. Calculate the Ea for the reverse reaction.

Expert Solution
