Review Problem 8.065 Construct an enthalpy diagram with the following data to calculate the electron affinity of bromine. The standard heat of formation of NaBr is -360.0 kJ molº?. The energy needed to vaporize one mole of Br2(l) to give Br2(g) is 31 kJ mol-1. Energy needed to vaporize one mole of Na(s) is 107.8 kJ. The first ionization energy of Na is 495.4 kJ mol-1. The bond energy of Br2 is 192 k) per mole of Br- Br bonds....

A. Calculate the lattice energy of NaI(s) using the following thermodynamic data (all data is in kJ/mol). Note that the data given has been perturbed, so looking up the answer is probably not a good idea. Na(s) ΔHsublimation = 88 kJ/mol Na(g) Ionization energy = 476 kJ/mol I-I(g) Bond energy = 131 kJ/mol I(g) Electron affinity = -315 kJ/mol NaI(s) ΔH°f = -308 kJ/mol kJ/mol Do you expect this value to be larger or smaller than the lattice energy of...
