Organic Reaction Mechanism [ENDORSED]

Hi,

For exercise #30, chapter 4 in the organic chemistry book, why won't the reaction occur at room temperature if the activation energy is 125 kj mol-1?

Thanks!

Re: questions 1.25-1.29

No, I think these topics will be covered in lecture next week.

Change in entropy in a substance

I was reading through the book and I did not fully understand the concepts behind the change in entropy in a substance going through one phase to another. I did not understand one of the three facts: how is the transfer of heat is reversible at the temperature of a phase transition? Thanks.
