Summary
Cobalt(II) soaps of general formula, Co(O2CR)2 (where R= C11H23 and C17H33) have been analysed by elemental analysis and i.r. spectra. Nonisothermal decomposition of these soaps has been studied by t.g.a. The activation energy, ΔE, frequency factor, Z, entropy, ΔS, and free energy, ΔG, are calculated and a probable mechanism for decomposition is proposed.
