answer parts e f g h 5) Using the Ellingham Diagram given answer parts e f g h

5) Using the Ellingham Diagram given below, a. Explain whether Cu2O can be reduced at 1000C by Nickel (Ni) or not. Why? b. Explain the reason why oxidation reactions of carbon have negative and zero slope (forming CO and CO2, respectively), whereas all the others have positive slope. c. What is the equilibrium Oxygen partial pressure of SiSiO2 reaction at 700C d. Which one ( Mg or Al ) has higher affinity to oxygen (oxidation)? e. Determine the Entropy and Enthalpy change of the TiTiO2 reaction. f. At what temperature the reduction efficiency of H2 and CO will the same? g. For SiSiO2 reaction, determine the equilibrium Pco/PCO2 and PH2/P2O ratio at 500C. h. Which one can be reduced easier (from its oxide), copper, silver or calcium? Why
