Donot pick 2 data points. This is less accurate and assumes all data points areequally qood.CorrectMarks for this submission: 1/1.6Marks: 1Answer:Calculate the pre-exponential term (in s -1).CorrectMarks for this submission: 1/1.2013F - CHEM126-Petrova: Chapter 13 Regular Homework: Kinetics II3 of 101/30/2014 11:41 AM

Make sure your units are consistent and use K.CorrectMarks for this submission: 1/1.8Marks: 1Answer:A catalyst decreases the activation energy of a particular exothermic reactionby 23 kJ/mol, to 38 kJ/mol. Assuming that the mechanism has only one step,and that the products are 26 kJ lower in energy than the reactants, sketchapproximate energy-level diagrams for the catalyzed and uncatalyzedreactions.What is the activation energy for the uncatalyzed reverse reaction?
