Answer to Question #75129 in Chemistry for Dev

Question

Calculate the lattice energy (in units kJ mol^-1)on eelectrostatic model and using a Born Haber cycle. Compare the two answers and comment on any difference Useful data :modelung constant (A) =1.6411,Born Constant(n)=8,internuclear distance (a) =199,Zn(s)+1/2O2->ZnO(s) ΔHf=-350.5kJ mol^-1 ,Zn(s)->Zn(g) ΔHs=130.4 kJ Mol^-1,Zn(g)->Zn+ I(Zn)=906.3 kJ mol^-1,Zn+ ->Zn2+(g) I(Zn+)=1733 kJ mol^-1,1/2O2(g)->O(g) 1/2ΔHd=248.5 kJ mol^-1,O(g)->O^-(g) EA(O)=141kJ mol^-1,O^-(g) ->O^2-(g) EA(O^-)=-780 kJ Mol^-1
