1. An energy maximum in a reaction-energy diagram would be labeled as which of the following?
c. Transition State
2. Which of the following best describes the shape of the methyl free radical?
The attached file is a typical activation energy diagram.
In this diagram,
1. Clearly you will see that the energy maximum is the transition state. So the answer is C.
2. Free radical in chemistry is a molecule or atom that contains an unpaired electron ...
The solution provides a detailed and step-by-step explanation (incl. reaction-energy diagram) for the problem.
