How to construct the energy level diagram and calculate the enthalpy of formation of WCl3?
given enthalpy change(E.C.)
E.C atomization W=+326.4kj/mol
E.C atomization CI = +121 kj/mol
E.C 1st ionisation W = +577.4 kj /mol
E.C 2nd ionisation W = 1816.6 kj / mol
E.C 3rd ionisation W = + 2744.6 KJ/MOL
E.C 1st electron affinity Cl = -384.6 kj/mol
E.C lattice energy WCl3 = -5492 kj/mol

http://en.wikipedia.org/wiki/Enthalpy_of_formation determinattion: reaction enthalpy for 1 mole from pure, "ground" state substances so firstly the basic equation and do you need to grow the apple before gravity pull it down as a analogy. alternative path building using hess law by summing reactions.
