Kinetics of electrocatalytic reduction of carbon dioxide by Mn catalysts containing bulky bipyridine ligands

In-Class Activity

Submitted by Kathleen Field, WPI

This question set has students examine the kinetics of the electrocatalytic reduction of CO2 to CO described in Sampson, D.L.; Nguygen, D., Grice, K.A.; Moore, C.E.; Rheingold, A.L.; Kubiak, C.P. Manganese Catalysts with Bulky Bipyridine Ligands for the Electrocatalytic Reduction of Carbon Dioxide:  Eliminating Dimerization and Altering Catalysis.  J. Am. Chem. Soc. 2014, 136, 5460-5471.

Learning Goals: 

Students will be able to...

  • Identify the experimental conditions required for the pseudo-first-order kinetics assumption to be valid.
  • Compare and contrast electrochemical and chemical kinetics.
  • Apply given experimental data to deduce the reaction order with respect to all reactants in the electrocatalytic reduction of CO2.
  • Calculate the rate constant (kcat) for a given set of conditions.
Equipment needs: 

Students should have access to a computer with Microsoft Excel.  



Implementation Notes: 

This can be adapted to a general chemistry/introductory class or can be used as in-class discussion with upper level students.  Secondarily this can be given as a homework asssignment and then used in class as a discussion or as an in-class acctivity.  



Time Required: 
one 50 minute class
Evaluation Methods: 

The assignment can be graded at the conclusion of the class period and then revisited at points later on an exam or at the final.
