Abstract The chlorination equilibrium of nickelous oxide has been investigated using the circulation method within the temperature range 666—928°K from both sides. The reaction is established as NiO(s)+Cl_2(g)=NiCl_2(s)+1/2O_2(g). The equilibrium constant and standard free energy of this reaction may be represented aslog K_p=(2720/T)-2.312ΔG_T~O=-12450+10.58 T.The result is found to be in good agreement with thermodynamic data in the literature. The maximum error for ΔG_T~O is estimated to be about +300 cal. At lower temperature, the experimental results of show some deviation from our data, probably due to unattainment of equilibrium in his experiments.
