Q1 We are investigating "cation vacancy-anion vacancy"-pairs in an unknown oxide ceramic(generalised chemical formula MO). Find solutions for parts a to c: (a) Determine the energy for defect formation (in

eV). (3 marks) (b) The equilibrium number of cation vacancy-anion vacancy defects per cubic meter at 1000°C. (2 marks) (c) What is the metal in this oxide ceramic (i.e., state the metallic element M)? (3 marks)
