Abstract
Kinetics of anation of cis-diaqua-bis(biguanide)cobalt(III) ion by glu tamic acid (LH) have been determined in mixed ethanol-water media. The low values of Delta H together with quite large negative values of D elta S are indicative of an associative interchange mechanism (I-a). The effect of solvent variation on rate also snpportsI(2) mechanism.
