Abstract

Reaction entropies of some metal complex redox couples in an amide-type room-temperature ionic liquid, 1-butyl-lmethylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) have been estimated by measuring the thermoelectromotive force at a non-isothermal cell. It is suggested that the reaction entropy is dependent on the difference in the charge densities of the oxidant and reductant of a redox couple, probably related to the coulombic interaction between the redox species and the ions composing the ionic liquid.
