## Abstract Secondβorder rate constants (__k__~2~) of the reaction between phenacyl bromide and equimolar mixture of nitrobenzoic acid(s)βtriethylamine have been determined in dimethylformamide (DMF)/acetonitrile (ACN)/acetone and aqueous mixtures of these solvents by conductometric method at 30Β°C.
## Abstract Salt effects on the reactions [Fe(CN)~6~]^4β^ + S~2~O^=^~8~ and [Ru(NH~3~)~5~py]^2+^ + S~2~O have been studied in media of different dielectric constants constituted by mixtures of water with organic cosolvents. It is known that salt and solvent effects are coupled and, consequently, ca
