Abstract
The lab experiment proposed for advanced undergraduate students deals with a comprehensive kinetic study of the hydrolysis reactions of [CoCl(NH3)5]2+. The experiment is aimed at increasing understanding of the differences between the spontaneous and assisted mechanisms operating for this dissociatively activated process. The differences should be related to changes in the energy of the starting material or transition state involved in the process; that is, the overall effect can be separated into contributions associated with ground-state and purely kinetic aspects.
