Extrathermodynamic analysis on the rate of equation of chloropentaminecobalt [III] ion in 10 acetone decarboxylate solution / acetone dicarboxylate solution

ABSTRACT

The rate of aquation of [Co[NH[3]][5]C1[2+]ion in aqueous dicarboxylate media of 10% [v/v] acetone has been studied in the temperature range, 30-60°C for six different types of dicarboxylate ions namely, succinate, malate, tartrate, malonante, maleate and phthalate. The ion-pair rate coefficient [k[ip]] has been estimated according to Wyatt and Davies treatment. The thermodynamic parameters delta G[ip] and delta S[ip]have been correlated with delta G o/ip and delta So/ip respectively, in a linear free energy and linear entropy relationships. Besides, the isokinetic relationship analysis reveals the existence of an entropy effect
