Calculate the lattice enthalpy of calcium oxide from the following data. Data found in the IB chemistry data booklet and the Born Haber cycle drawn in part (a) enthalpy of atomisation of Ca_((s)) = + 178kJ mol^(-1) second ionization energy of Ca_((g))= +1150 kJ mol^(-1) enthalpy of formation of calcium oxide = -635 kJ mol^(-1 ) |
