Solvent effects on the kinetics of aquation of [Co(dien)(en)Cl] have been investigated within the temperature range (40 -60Β°C) in acetone-water and ethanol-water media of varying solvent compositions up to 60% by weight of the organic solvent component. The variation of the activation parameters (β¬G
## Abstract The aquation of Kβ[Co(dien)(en)Cl]^2+^ was followed spectrophotometrically within the temperature range (40β60Β°C) in water, waterβisopropyl alcohol, and waterβ__tert__βbutyl alcohol media of varying solvent composition up to 50 and 60 vol% of the organic solvent component respectively.
