Abstract  The chlorination equilibrium of cobalt sesquioxide has been investigated by the circulation method. Within the temperature range 673—923°K, the equilibrium constant and the standard free energy of the reactionCo_3O_4(s)+3Cl_2(g)=3CoCl_2(s)+2O_2(g) have been found to belog K_p=(404/T)-0.304,ΔG_T~O=-1850+1.39 T.or log K_p=(4509/T)+12.28 log T-41.13,ΔG_T~O=-20630-56.2 T log T+188.2 T.The thermodynamic data reported in previous literature are very divergent. They are critically examined and compared with our data.
