Was reviewing some of my physical chemistry lectures and attempted a a derivation of the unimolecular gas phase reaction using a calculation based on the RRK model (Rice-Ramsperger-Kassel), and ran into some trouble half way into the derivation. My Derivation I have a unimolecular gas phase re...

This question was posted 2 days ago, closed yesterday as being too broad and reopened today. The question has never been edited so its contents are the same throughout. I wonder why people voted to reopen it and why that vote subsequently went through. The question asks whether there is a chemic...

Firstly a note about terminology. The word "terminus" is reserved for the N- or C-termini of a polypeptide chain. For a free amino acid, you should refer to the carboxyl and amino groups as the $\alpha$-$\ce{COOH}$ and $\alpha$-$\ce{NH2}$ groups respectively. Anyway, the -$\ce{COOH}$ group is ac...
