By looking at the figure 1, gravity acts downwards on the flats surface. (b) Basic nature of the ligand: A more basic ligand will form a more stable complex. 27 Instability factors include coalescence, flocculation, and phase separation. When moisture is present, the solid drug decomposition may change to zero-order chemical kinetics because the rate is controlled by the relatively small fraction of the drug that exists in a saturated solution, which is located (usually imperceptibly) at the surface or in the bulk of the solid drug product. endstream Tap here to review the details. 0000001016 00000 n Thus, chemical stability has implications for both the thermodynamics and kinetics Please enable it to take advantage of the complete set of features!
