Homework Help: Physics

Posted by Anonymous on Tuesday, February 5, 2013 at 10:51pm.

The activation energy for the isomerization ol cyclopropane to propene is 274 kJ/mol. By what factor does the rate of this reaction increase as the temperature rises from 256 to 297 oC? (The factor is the ratio of the rates.)


A catalyst decreases the activation energy of a particular exothermic reaction by 60 kJ/mol, to 27 kJ/mol. Assuming that the mechanism has only one step, and that the products are 46 kJ lower in energy than the reactants, sketch approximate energy-level diagrams for the catalyzed and uncatalyzed reactions.

What is the activation energy for the uncatalyzed reverse reaction?


So I'm not sure how to do either of the questions. I've looked through my notes and the book, but I still can't get it. Thanks in advance!
