The voltages versus Li measured in Li-Co-O system are shown in the ternary phase diagram. The Gibbs free energies of pure substances (unit kJ/mol are G(Li) -8.67, G(Li₂O)=-610.027, G(COO)=-253.737, G(C0304)=-944.101. E₂=1.636 V Li Li₂O Oxygen LiCoo₂ E3-3.9 V V C0304 Coo E₁=1.807 V Co a) Calculate the Gibbs free energy of LiCoO2 Compound. b) Calculate the Gibbs free energy of CoO2 compound. c) Calculate the voltage vs Li in the C0304-C0O-LiC0O2 sub-triangle.
