Collision and transition state theory approaches to acid-base catalysis Dunford, H. B.
Shows that the description of acid-catalyzed chemical reactions in terms of transition state acid dissociation constants is formally equivalent to the collision theory approach, in which dissociation constants of acid groups on initial reactants are utilized.
