Hydrolysis of Pentaamminechlorocobalt(III): A Unified Mechanistic View
Gabriel González and Manuel Martínez
Departament de Química Inorgànica, Universitat de Barcelona, E-08028 Barcelona, Spain

November 2005
Vol. 82 No. 11
p. 1671
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.
Supplement
Instructions for the students and notes for the instructor are available.
