Calculate the lattice energy of TlBr(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.
Tl(s)
ΔHsublimation = 161 kJ/mol
Tl(g)
Ionization energy = 569 kJ/mol
Br-Br(g)
Bond energy = 173 kJ/mol
Br(g)
Electron affinity = -345 kJ/mol
TlBr(s)
ΔH°f = -193 kJ/mol
Do you expect this value to be larger or smaller than the lattice energy of TlI(s)? _________larger smaller
