Abstract

This paper describes an addition to a previously published experiment in which NMR is used to follow the kinetics of the reaction of trifluoroacetic acid with alcohols. A variable temperature accessory is used to determine the energy of activation and reaction order with respect to the alcohol concentration. Students are asked to correlate steric factors with reactivity based on experimental results.
