Based on the activation energies and frequency factors, rank the following reactions from fastest to slowest reaction rate, assuming they are all at the same temperature and that each starts with the same initial concentration.

Draw a graph showing the reaction pathway for an overallexothermic reaction with two intermediates that areproduced at different rates. On your graph indicate thereactants, products, intermediates, transition states, andactivation energies.
