Use a Born Haber cycle to calculate the lattice energy (in Kj/mol) of the compound (AB) from the following data:lonization energy of A(g) = 420.08 kJ/molElectron affinity of B(g) = -343.36 kJ/molEnergy to sublime A(s) = 81.54 kJ/molBond energy of B2(g) = 258.42 kJ/molEnthalpy for the reaction A(s) + 1/2B2(g) --> AB(s) = -436.60 kJ/mol(Enter only your numeric answer, do not include units, do not use scientific notation, include 2 decimal places with your answerHINT: Lattice energy is defined as the energy that must be supplied to break apart an ionic compound, so your value should be entered as a positive value.When you submit your work for this week show all the steps you used to calculate your answer.
