The Rate of Racemization and Isomerization of the cis-Chloroaquobis(ethylenediamine) cobalt(III) Ion

Abstract

The rate of isomerization of the cis-chloroaquobis(ethylenediamine)cobalt(III) ion to the trans-isomer k_30° = 2.7 x 10^-3 min^-1 has been shown to be the same as the rate of racemization k_30° = 2.61 x 10^-3 min^-1. The activation energies and entropies for the reactions are AE_a = 27 ± 1 kcal/mole, AS? = $2 e.u., and ΔE_a = 26.7 ± 0.2 kcal/mole, AS? = +2.3 e.u. respectively.
