Abstract
The kinetics experiments on the ligand-C60 exchange reactions on (dihapto-[60]fullerene) pentacarbonyl tungsten(0), (η2-C60)W(CO)5, form an educational activity for the inorganic chemistry laboratory that promotes graphical thinking as well as the understanding of kinetics, mechanisms, and the temperature dependence of rate constant values. It provides an opportunity for students to apply the concept of activation parameters to confirm or disprove a proposed mechanism and the relation between activation enthalpy and activation energy with the thermodynamic bond enthalpy and bond energy, respectively.
Supplement
Instructions for the students and notes for the instructor are available.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
