Consider the following data.
DeltaHf (Na2O (s))=-414kJ/mol
Delta H sublimation(Na)=109 kJ/mol
I.E. (Na)=495 kJ/mol
Bond Energy (O2) = 495 kJ/mol
E.A. (O) = -141 kJ/mol
E.A. (O -) = 878 kJ/mol
Use this information to calculate the lattice energy of Na2O (s).
So, we have the total which is delta H f (-414kJ/mol) and delta Hf= Delta H1+deltaH2+,...,+x
Where x is the lattice energy. I am still struggling in finding x
