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.
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.
Students should have access to a computer with Microsoft Excel.
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.
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.
