7E.3

[Gabriella Bates 2L]

"The presence of a catalyst provides a reaction pathway in which the activation energy of a certain reaction is reduced from 125 kJ*mol^−1 to 75 kJ*mol^−1. (a) By what factor does the rate of the reaction increase at 298 K, all other factors being equal? (b) By what factor would the rate change if the reaction were carried out at 350. K instead?"

Can someone explain how to do this problem? The way they solved it in the solutions manual is slightly different than the example in the textbook, and I'm struggling to understand how they solved it. Thank you!

The textbook does an example in the reading, and it uses the equation Ea is the activation energy. Substituting the known values should result in the correct answer for part a. For part b, you use the same equation but with a different temperature. Let me know if you still have any questions
